We are getting attached error like "Error: Error in provider Thumb info not found" while display some images using MultimediaViewer extension.

Also the thumbnails images on WIKI page are not updated when ever upload the latest version of the image

Though We are using following versions of software(s) in TEST as well as PROD environments. yet, we don't see the multimediaViewer display issue in our test environment. Please suggest resolution for this issue.

Installed software

Product Version
MediaWiki 1.30.0
PHP 7.1.8 (apache2handler)
MySQL 5.6.40
ICU 50.1.2

MultimediaViewer Error

Finally I could able to resolve the Multimedia Viewer display issue.

Actually the issue was occurred for some of newly updated PNG images on the page. And it could be because of insufficient Shell memory

So , I have configured and set following param values in LocalSettings.php on par with our Server configuration . And now I see the issue is no more exists !!!

$wgMaxShellMemory = 8000000;

$wgMaxShellFileSize = 1000000;

$wgMaxShellTime = 300;

Moreover we are in process to upgrade our existing MediaWiki 1.30.0 to the latest LTS version of MediaWiki 1.31.1. So, I would believe the issue with thumbnail creation for new version images in this MediaWiki 1.30.0 is fixed for this LTS version of MediaWiki 1.31.1.

Extension:RSS bug? Does not seperate RSS items

Semako96 (talkcontribs)

I want to include the latest topics of my forum within a wiki page and used RSS for that:

The problem however is, that, after configuring Extension:RSS so that it displays links and images within the RSS descriptions, the items aren't seperated properly when the previous item's description ends with an image like a smiley.

I tried workarounds by adding divs and spans to the MediaWiki:Rss-feed template (which I also want because it makes styling with CSS much easier), but that doesn't work either, the div and span tags don't get included in the source code of the RSS feed on the wiki page.

Is there another workaround for this bug?

Semako96 (talkcontribs)


Ciencia Al Poder (talkcontribs)

The wiki is rendering bad HTML markup. This is caused by the fact Extension:RSS is truncating the contents of each item to a fixed number of characters, but it's not respecting HTML tags. In one case, it truncates in the middle of the URL of an <img> tag, causing tags and attributes to not be properly closed.

You can try raising item-max-length to the maximum to prevent this.

Block user or group to view pages

2610S (talkcontribs)

How can I block a user or a group from viewing pages without getting the pages with a Namespace?

AKlapper (WMF) (talkcontribs)
2610S (talkcontribs)

Looking for pages with access by group, so each group can se there pages, but without namespace

AKlapper (WMF) (talkcontribs)

I don't understand. What is "without namespace"? What does "viewing pages with getting the pages" mean?

2610S (talkcontribs)

"viewing pages with getting the pages" mistake it should be "without"

changed above

2610S (talkcontribs)

I know that I can use this page Manual:$wgNamespaceProtection but then I need to get all pages with Namespace for Ex 1:main page.

so i'm looking for a solution without Namespace

If I want to use this

Disable reading by anonymous users

$wgGroupPermissions['*']['read'] = false;

# But allow them to read e.g., these pages:

$wgWhitelistRead = [ "Main Page", "Help:Contents" ];

can I write add $wgGroupPermissions['user']['read'] = false; ,how will the system know to restrict not registered users from all pages, and the whitelist should only be for 'user' ?

And how will the system know that users in Group 1 can read all pages ?

AhmadF.Cheema (talkcontribs)

The asterisk (*) means anonymous users. $wgGroupPermissions['*']['read'] = false; will restrict reading by unregistered users. Pages mentioned in $wgWhitelistRead are viewable by all users.

What is "Group 1" here?

Note that, "If you need per-page or partial page access restrictions, you are advised to install an appropriate content management package. MediaWiki was not written to provide per-page access restrictions, and almost all hacks or patches promising to add them will likely have flaws somewhere, which could lead to exposure of confidential data."

Ciencia Al Poder (talkcontribs)

There's no reason to prevent registered users from viewing pages that anonymous users can read. Think about it. A blocked user can just logout to get access!

Multiline tooltip from inside wikitext

Taylor 49 (talkcontribs)

It's sufficiently easy to brew a primitive single-line tooltip:

<span title="British Rail">BR</span>

But the method stops being useful with longer texts. How can I brew a multiline tooltip? Using "<br>" inside "<span>" is not possible. There is the "hover" CSS selector that can brew sophisticated and multiline tooltips, but I can't find a way to use it from wikitext.

Is there a way to brew a multiline tooltip from inside wikitext?

AhmadF.Cheema (talkcontribs)
Taylor 49 (talkcontribs)

Thanks ... I forgot to mention that I need a method for Wikimedia public wikies. "Extension:SimpleTooltip" is extremely promising but doesn't seem to be enabled on public wikies. I don't understand the "Extension:Cite" and "refn" hint. Is there a method feasible for public wikies?

AhmadF.Cheema (talkcontribs)
Taylor 49 (talkcontribs)

OK, thanks. I wonder whether there is a chance to get "Extension:SimpleTooltip" enabled on a public wiki via phabricator bugzilla?

Trying to test conditional formatting in preview, but not triggering correctly.

If then scenarios, nothing complex. Is this a known problem?

Is this related to MediaWiki? (talkcontribs)

Oh I guess you just support their user manual wiki,not the applications. Sincerest apologies
