I have a page on 9738 words and 73074 characters.

VE loads to 100% (pretty quickly) and stops there and nothing happens.

When I trimmed it down to around 50k characters it worked.

Sounds like there is a limitation somewhere that restricts this?

Any ideas?

Blazyb (talkcontribs)

Problem identified: It was a thumbnail that VisualEditor cannot parse. Why is that?

Blazyb (talkcontribs)

Error msg:

Whatamidoing (WMF) (talkcontribs)

Hi @Blazyb. Is this on a private wiki? Is the image present on the local wiki, or pulled from somewhere else?

Blazyb (talkcontribs)

Yes, this is a private wiki. The image is present on the local wiki yes, it is uploaded through the "Upload file" page. And checking the images folder I can see the files there. (talkcontribs)

Hey Blazyb did you found a solution?

My VE is loading as well but stops at 100%.. But only in Pages with Images

Maalab (talkcontribs)

I got the same error. Anyone have a solution?


Maalab (talkcontribs)

I have discovered something. Our Wiki is in french. If i put this in my LocalSettings.php, it work : $wgLanguageCode = "en";

I have not find a solution to use it in french.

Whatamidoing (WMF) (talkcontribs)

Maalab, can you please tell me more about your config? Also, what version are you using for VisualEditor, Parsoid, and MediaWiki?

I've named you in the bug report at Phab:T155447. You can provide more information on this page or directly in the Phabricator task.

Maalab (talkcontribs)

Thanks Whatamidoing for your reply. I will reply to both place so people can follow this case.

Our wiki is run on Ubuntu 14.04.5 LTS server. Parsoid version is 0.6.1, Mediawiki version is 1.27.1 LTS and VisualEditor version is 0.1.0.

This is a private Wiki, but i have change it to a public Wiki and the problem is still there.

We have some extensions, but i will not list them (except if you need it), because when i disable them all, this does not solve the problem.

I don't think the problem is related to parsoid, because, when i troubleshoot parsoid and show the page in problem (http://servername:8142/localhost/v3/page/html/Test/), everithing seems to work fine and there is no error un parsoid log.

The only way i get VisualEditor to work with a page that have an image aligment, is when i put the Wiki in english. Our Wiki is in french.

When i inspect the code with Chrome Debugger, i get this error : Uncaught TypeError: Cannot read property 'constructor' of null at Object.oo.cloneObject.

I have also report this bug at

Let me know if i can test something to help troubleshoot.

Screenshots on this page look like some older version of topbar, could someone update them?

Whatamidoing (WMF) (talkcontribs)

I don't see any screenshots on this page (i.e., VisualEditor). Can you give me a link to the page that you're talking about?

VE is garbling wikilinks as an drive-by-accident

Sänger (talkcontribs)

In this change it seems, the VE has changed some correct wikilinks to something not readable in normal edit mode. The IP probably only wanted to update the table (and messed it up, despite VE is supposed to be better in working with tables), it would never have made those other changes intentionally. As I can't start a phab, I report it here.

The paragraph on deWP where this popped up was this one.

Why isn't the VE running on talk pages anywhere?

Summary last edited by Sänger 21:00, 13 July 2016 6 months ago

There won't be any real answer at any time.

Sänger (talkcontribs)

Instead of the normal editing possibilities, on talk pages we are restricted to either only use the wikitext editor, or to this Flow environment, with its massive restrictions on next to everything. Why is the VE not enabled anywhere on talk pages?

Jdforrester (WMF) (talkcontribs)

Hi there. This question comes up a bunch, and has been answered at length a few times before, but I can't find any of those right now, sorry.

The short answer is that VE is a content editor, and is designed to make writing (long-form) content. In dozens of ways, we've optimised it around writing articles for Wikipedia, Wikivoyage and other wikis. The use cases of a semi-free-form-but-with-odd-rules discussion box are fundamentally incompatible. Providing VE for talk pages would mean making massive compromises both on being a good content editor and on being a good discussion editor. It's an anti-pattern, and it's not going to happen.

I know you have a personal animus with Flow, and that's unfortunate, but it's the option available if you think talk pages don't work well (with which I would agree).

Sänger (talkcontribs)

It's just about an editor, the difference between a plain text editor and a wysiwyg editor. There shouldn't be any big difference between editing a text on either the front or the back side of any page. A talk page is as well nothing much different to any other content page, only the content is a bit different.

It's like the difference between old fashioned WordPerfect and the wysiwyg version of the same program. Some prefer the classic mode, some the ve, but the resulting page is just the same.

Sänger (talkcontribs)

Why was this definitely not solved question closed? Your answer was just a straw man, not a real one. It's everything but closed.

Jdforrester (WMF) (talkcontribs)

Sorry, I didn't see a question in your response, just implicit accusations of bad faith and incompetence. :-) If you could re-write one that'd be great, otherwise there's nothing more to say.

Sänger (talkcontribs)

Why isn't the VE running on talk pages?

VE is a text editor, and thus should be fully capable of editing on any page, at least simple talk pages.

Jdforrester (WMF) (talkcontribs)
VE is a text editor,

As I explained, this is not true.

Sänger (talkcontribs)

To just quote the first sentence from the other side:
The VisualEditor project aims to create a reliable rich-text editor for MediaWiki.
So why do I have the impression, that either the other side is plain wrong or your "argument" is just a straw man?

Whatamidoing (WMF) (talkcontribs)

The visual editor cannot (abuse HTML definition list formatting to) fake the indentation of paragraphs. Therefore, you are likely to find using it in a talk-page discussion to be frustrating at this time.

Sänger (talkcontribs)

...yet. An editor that's capable of editing tables, using templates, setting references etc.pp. is incapable of abusing colons for indentation? Should I really believe this?

Why do I think of a nice idea to push the software pet project that's not as much liked by the community as by the WMFers?

Whatamidoing (WMF) (talkcontribs)

I think you may have to wait until phab:T6521 is resolved.

BTW, there are a few wikis that have the visual editor enabled in the Project: namespace, and which also have some discussions in that namespace (e.g., ), and we hear complaints about problems on those pages. I don't think that it would be a good idea to expand the use of the visual editor on such pages at this time.

Sänger (talkcontribs)

You insist without any real merit, that a wikipage is not the same as a wikipage. In principle all wikipages behave in absolutely the same manner, they were edited with exactly the same editor up to some time ago, when you a) tried to get so-called structured discussions, first with Liquid Threads, something that failed, now with a bit different layout system Flow, something that as well is stuck in limbo. But if you discount these, the article page uses the same syntax as the talk page, the user page uses exactly the same syntax as the talk page, with one of two available editors the can be edited in exactly the same way as everything else in the wikiverse. With the other one, the VE, you claim that these exactly same pages are magically somehow different, and one of them can't be edited in a wysiwyg-way.

BTW: Using colons to indent, instead of some software hack created by those many devs paid by content creators and talk page users, is frustrating as well, but you choose to ignore this for quite some time and preferred to create shiny new bling instead of boring maintenance. That's at the core of this, not the proclaimed, but not existing, differences between those pages. And the phab is just a strawman as well, if you mange to get templates programmed somehow, the indentation problem should be non-existing. Unles you deliberately choose not to do something about it, to keep this strawman alive.

MZMcBride (talkcontribs)

Hmmm. Does "support VisualEditor on talk pages" have an associated Phabricator Maniphest task?

I tend to agree with Sänger, though I'd perhaps phrase it this way: VisualEditor should work with all regular (non-Special) wiki pages. This includes user pages, talk pages, portal pages, pages in the MediaWiki namespace, etc. It's an extensible editor that we've already installed and committed to supporting. We've seen time and again that the arbitrary distinction put up between VisualEditor support by namespace is confusing and annoying to users.

I think there are talks about unifying the wikitext and VisualEditor editors. Eliminating or masking the difference between the two or more editors that we have may somewhat neatly resolve this issue.

Whatamidoing (WMF) (talkcontribs)

To see the result of these "talks", go to Special:Preferences#mw-prefsection-betafeatures and enable the "new wikitext mode" beta feature.

NB that it's not really about "unifying the [old] wikitext and VisualEditor editors". This will not merge the code for EditPage.php or Extension:WikiEditor with Extension:VisualEditor. The only thing that's being unified is the user experience, i.e., the user gets VisualEditor's black-and-white toolbar and VisualEditor's built-in tools (such as pasting a URL to a Wikipedia page and getting an internal wikilink instead of an external link) everywhere. There will still not be any visual mode on the talk pages.

Sänger (talkcontribs)

And there is still no believable reason given, why a wikipage is not a wikipage. It's just futile justification lyricism for not wanting to do anything against Flow.

Reply to "Why isn't the VE running on talk pages anywhere?" (talkcontribs)


We have now got VE up and running (on Mediawiki 1.27) but have some complex InfoBoxes that just don't look too good in VE. There is no requirement for my users to change these in VE as we use SMW properties and forms to control all Infooxes. Is there any way I can exclude portions of text or even sections from VisualEditor on a given page when VE is launched via the Edit button.

Any help appreciated.

Jongfeli (talkcontribs)

Please read: (talkcontribs)

Thank you for the response. Looks like we are out of luck. The __NOVISUALEDITOR__ seemed like a really good idea for full page VE disablement. To be honest I was hoping for one better and was hoping there was going to be <novisualeditor> </novisualeditor> set of tags, similar to the tag in concept. I will mention to the SMW team to see if they have any ideas. Once again thanks.

JJBers Public (talkcontribs)

I use both the WikiMarkup editor and the VisualEditor all the time, I was edit a project page for a while, and when I went to a article to make a small grammar fix, I noticed something, whenever you are finished editing, after you type in the edit summary, the enter key doesn't save the edit. What I'm saying is that I wish the enter key would work for at least the major Wikipedias in the VisualEditor some time soon. I don't know how hard this will take, but I hope it isn't too long to integrate.

Parsoid crashes when processing articles with codeblocks

Satttarov (talkcontribs)

Hello, folks! When I create an article in our private wiki with more then four codeblocks, save it and try to edit later, those codeblocks aren't appear in editor. And when I close the editor, page freezes for about a minute then pass. But if I try to launch editor on this page again it crashes with error "HTTP 0" on parsoid logs I see this:

Somebody encountered the same problem? Please help, this error completely defeats the purpose of our wiki.

Whatamidoing (WMF) (talkcontribs)

@SSastry (WMF), have you seen anything like this before?

SSastry (WMF) (talkcontribs)

I haven't seen this before ... but, can you paste the contents of that page for us to inspect? Looks like mediawiki is not able to provide information back to Parsoid ... either it is taking too long and timing out, or there is some other error that is causing this on the mediawiki end.

Satttarov (talkcontribs)

For the sake of testing I'm using these blocks. It doesn't matter what those blocks contain, if there is more than four blocks, Parsoid hangs as I described before.

<syntaxhighlight lang="bash">



Thanks in advance.

Arlolra (talkcontribs)

At first glance, that looks like a deadlock.

Do things get worse when you remove batching?

parsoidConfig.useBatchAPI = false;

Is this specific to the syntaxhighlight extension? What if you tried with <source>?

Arlolra (talkcontribs)

Sorry, <source> wasn't a good test case. I wanted an extension tag not provided by the same extension. Try <gallery>.

Reply to "Parsoid crashes when processing articles with codeblocks" (talkcontribs)

Hello Can any body take care about the ticket I've already open at :

the question is that I can see VisualEditor running in my wiki with the configuration I've describe, I do not

Know what is the problem.

Thanks in advanced. (talkcontribs)

I still have the trouble , you can see in the link, any help?, thansk.

Whatamidoing (WMF) (talkcontribs)

Are you running "matching" versions of MediaWiki, VisualEditor, and Parsoid? Your note on Stack Overflow said that you're running MediaWiki 1.26.2 but did not (AFAICS) mention the version numbers for the extensions. (talkcontribs)

I'm running mediawiki version 1.27.0;

the visual editor I've downloaded from the visualeditor page form mediawiki with:

cd extensions git clone cd VisualEditor git submodule update --init (talkcontribs)

I'm thinking I am not using the correct version of parsoid, nodejs and VisualEditor with work right all together with de mediawiki 1.27.0 version.

Any help?, thank you very much (talkcontribs)

I would apreciate if any body can give me the links and the correct protocol to dwonload and install the correct version of parsoid, nodejs and VisualEditor for mediawiki 1.27.0, thanks in advanced.

Whatamidoing (WMF) (talkcontribs)

I don't know how to install the software myself. If we're lucky, someone else will be able to help us.

Whatamidoing (WMF) (talkcontribs)

I had a look at the documentation, and this might be what you want:


Special:ExtensionDistributor/VisualEditor (talkcontribs) (talkcontribs)

I'm afraid this wiki documentation or wiki does not show the correct protocol to install the visual editor, I've spent a lot of time trying without result, I'm thinking about change the product for a wiki, does not give me the correspondent support or help.

the documentation of this wiki is so rolled that is imposible to configure this extension, is not clear at all, apart of that I think there woul be a wiki page describing the complete protocol to install the 3 products , nodejs with the correct version of each SO, the correct version of parsoid for each SO and nodejs and mediawiki, and finally the correct version os visual Editor Extension.

Whatamidoing (WMF) (talkcontribs)

I'm sorry that it's so frustrating. As I said, I don't know how to do it myself. The WMF can't provide support to other people's wikis. Perhaps it'd be possible to find a consultant, or advice from a user group? (talkcontribs)

What we need is a step by step install Wiki+VisualEditor/Parsoid for CentOS7 and Ubuntu. I am too spending a LOT of time trying to get it to work.

Nowhere does it say how and where to download the appropriate versions of MediaWiki/Parsoid (how is the pairing working, any list of versions that work?)

Whatamidoing (WMF) (talkcontribs)

If you figure it out, then please feel free to start a doc page here.

I've heard that the versions of MediaWiki, VisualEditor, and Parsoid must all match (so if you do 1.27 for one, then you have to do 1.27 for all three of them).

Hello, did anybody succefully integrate VisualEditor with any video player plugin? I tried EmbedVideo, but it nor show thumbnail in editor, nor allow to enter resolution for video, though allows to insert mediafile into page.

Jdforrester (WMF) (talkcontribs)

Not yet, sorry. The one used in Wikimedia production is Extension:TimedMediaHandler, which we will work on ahead of others' working I imagine, but it doesn't integrate neatly yet.

Question about the "Single Edit Tab" feature

Guycn2 (talkcontribs)

Hello. When will the "Single Edit Tab" feature come to Wikibookses ?

Elitre (WMF) (talkcontribs)

I don't think there's anything planned ATM. Are you aware of a specific Wikibooks which really wants it?

Guycn2 (talkcontribs)

What a shame... I would personally want it on the Hebrew Wikibooks, but I'm not sure the community supports it...

Is there any plan to enable this feature on Wikipedias? (I mean on all Wikipedias, not just ones that ask for it particularly like the Hungarian Wikipedia)

Whatamidoing (WMF) (talkcontribs)

The team is re-thinking the system for this feature. I don't know when they'll update it next, but they're not currently planning to deploy it to any place that already has the visual editor for all users until they've decided whether it needs to be refined.
