When I upload images it will not provide a thumbnail image. I read through various posts and understand many shared servers have blocked proc_open and seems mine is that too. I turned imagemagik to false and default to GD which is active on my server but imagemagik is not but still thumbnail is not showing and gives the error

I have also noticed proc_open also affecting scribunto and the lua file as shown here

Despite searching I cannot seem to find an alternative to fix the image thumbnail issue and the lua issue

I am sure there is a workaround about that will fix this as I cannot be the only one who has this blocked on their server.

i can ftp the main directory but have no access to the root otherwise i would have changed php.ini myself. I also added a flag command to .htaccess to see if i could activate proc_open that way but that did not work.

I have also noticed that version MediaWiki 1.23.15 the thumbnails work fine with imagemagik false yet when same setting is on 1.27 it fails.

First Login Issue: Problem with Sending Credentials

MarcelDueerkop (talkcontribs)

Hello Everyone, I know this is a long read but please help, I am edging towards insanity. I have setup Media Wiki on a few Virtual machines to play around with without any issues. Now I want to get it running on my ODroid XU4 with eMMC running a Debian called Armbian. MediaWiki version 1.27.1

Whenever I try to login (for the first time) it gives me a session error: "Es gab ein Problem bei der Übertragung deiner Benutzerdaten. Diese Aktion wurde daher sicherheitshalber abgebrochen, um eine falsche Zuordnung deiner Änderungen zu einem anderen Benutzer zu verhindern. Bitte gehe zurück zur vorherigen Seite, lade sie erneut und versuche, den Vorgang erneut auszuführen." This translates to There was a Problem with sending your login credentials. To Prevent damage to others the action has been interrupted.... refresh and try again.

Sadly refreshing does not work.

To try and solve the Issue I have tried the following steps:

1) PHP can write to the Sessions Directory, there are files being created.

2) Added session_save_path("tmp"); to the LocalSetting.php file and created the folder. Error still persists. The folder permissions were set to 777.

3) $wgSessionsInMemcached = true; # optional, still the same error

4) Checked if there is enough Disk Space, there is.

5) Added All Privileges to wikiuser on the Database

To try to figure out more I have turned on Logging with the following result from a login try:

I fail to see an error here, only that things are being marked "dirty"

I've been running Mediawiki 1.27 for some time now. Few days ago I was receiving an error in the browser saying that my website cannot be reached. So navigated to mw-config to reconfigure it. Went through the process quiet well, but after that I started getting error messages on every page. The Internal error message is below. I tried to reinstall Mediawiki but nothing has worked.

Please help! You can have a look at my website here:

Internal error

[V8LDn8ZH7RYADTL@JGAAAAEN] 2016-08-28 10:57:35: Fatal exception of type "MWException" (talkcontribs)

Please enable $wgShowExceptionDetails at the bottom of your LocalSettings.php! (talkcontribs)

Thanks a lot. I displayed the errors and it pointed to Scribunto. I reinstalled it and everything is working fine. Appreciated.

Which file is responsible for top navigation panel? (Talk, Log in, Create acount, etc..) because I would like to modify the path for "Create acount" from the standard url to for example: (talkcontribs)

You do not want to modify core files. Instead, there are various personalization extensions, which can modify this band of links by adding functions to the PersonalUrls hook. Category:PersonalUrls extensions contains a list of available extensions.

Apart from that you can also write an own hook function in LocalSettings.php.

Firmware not able to update?

Summary by Jackmcbarn

Completely unrelated to MediaWiki

RadioSlavesSuck (talkcontribs)

I just bought a new MiniTT1. I followed the instructions. Step 5 says Under the Update Tab, click "Check for Updates", which will download the latest firmware version, and prompt to update the firmware in the connected radio.  That button does not appear on my screen and the MiniTT1 does need to be updated.

Hi, this is the helpdesk for the MediaWiki software project. I don't think we can help you with your problem.

It's not possible for MediaWiki usernames to begin with a lowercase letter.

Joriandrake (talkcontribs)

Hello, I just made an account, for some reason my first letter is large, I may have accidentally done this myself, any way I can make the j small as well? (talkcontribs)

The answer is: No, you can't. :-(

Usernames in MediaWiki have some restrictions, e.g. they cannot have underscores in them and their first letter always is in uppercase. Also they cannot have special combinations of characters in them, e.g. "../" is not possible as that would make the user page unreachable.

However, depending on in which wiki you are, there at least is a small help: Some wikis allowusing a magic word to change the display of the page title of a page.

E.g. you could add


on top of your user page and your user talk page. If you add that on your user page, then the page at least will display the name in the spelling with small j.

Почему бессрочно заблокировали мою учётную запить Main Guns ?

Question about a block on Commons, not a MediaWiki software issue

Main Guns (talkcontribs)

Почему бессрочно заблокировали мою учётную запить Main Guns ? -

Создавал страницу с учётом всех требований википедии, за что получил блокировку , как я могу исправить / восстановить учётную запись?

Спасибо. С Уважением Иван Кичук. Разработчик игры Main Guns ( (talkcontribs)

Hi Ivan,

I understand that you are asking why your user account Main Guns got blocked on Commons.

The block was done by commons:User:INeverCry. The block reason, which he provided was "promotion-only account". Background for this block is the content of your (deleted) user page, which the admin considered promotional. Note that Wikipedia Commons is no place for promotional materials. Having posted this page is the reason why your account got blocked.

TheDJ (talkcontribs)

Hi, you posted to the helpdesk of the software project MediaWiki. Your question seems to pertain to something other than our project, so unfortunately, we won't be able to help you.

I added some SVG files.

But now I see on page when that files are added this error:

"Error creating thumbnail"

I have that code in LocalSettings:

$wgFileExtensions = array( 'png', 'gif', 'jpg', 'jpeg', 'ppt', 'pdf', 'psd', 'mp3', 'xls', 'xlsx', 'swf', 'svg', 'doc','docx', 'odt', 'odc', 'odp', 'odg', 'mpp');

$wgSVGConverter = 'ImageMagick';

$wgAllowTitlesInSVG = true;

$wgSVGConverterPath= "C:/ImageMagic/convert.exe";

$wgLoadFileinfoExtension = true;

$wgMimeDetectorCommand = "file -bi";

I'm not sure about that:

$wgSVGConverterPath= "C:/ImageMagic/convert.exe";

Does that mean that I should have installed ImageMagic on my PC? (talkcontribs)

That means that you should either remove the wrong configuration so that MediaWiki will no longer try using a program, which is not there thus throwing an error. Or you should install ImageMagick and make the path point to it.

The first $wgSVGConverterPath is superfluous and should be removed no matter what you decide to do.

TraaBBIT (talkcontribs)

OK. But should I install ImageMagic on my PC or on server? (talkcontribs)

If, then on the server.

TraaBBIT (talkcontribs)

OK. I installed IM on my serwer.

I got this error now:

Error creating thumbnail

/bin/bash: /usr/local/bin/convert/convert: Not a directory


Ciencia Al Poder (talkcontribs)

Whenever you have /usr/local/bin/convert/convert in your LocalSettings.php, it should probably be /usr/local/bin/convert or even /usr/local/bin

TraaBBIT (talkcontribs)

I have this settings in LocalSettings.php:


$wgUseImageMagick = true;

#$wgImageMagickConvertCommand = 'C:/ImageMagick/convert.exe'; # for windows

$wgImageMagickConvertCommand = '/usr/bin/convert'; # for linux


$wgFileExtensions = array( 'png', 'gif', 'jpg', 'jpeg', 'ppt', 'pdf', 'psd', 'mp3', 'xls', 'xlsx', 'swf', 'svg', 'doc','docx', 'odt', 'odc', 'odp', 'odg', 'mpp');

$wgSVGConverter = 'ImageMagick';

$wgAllowTitlesInSVG = true;

$wgSVGConverterPath= '/usr/local/bin/convert';

$wgLoadFileinfoExtension = true;

$wgMimeDetectorCommand = "file -bi";

I got this error on pages:

Błąd przy generowaniu miniatury /bin/bash: /usr/bin/convert: No such file or directory

Error code: 127 (talkcontribs)

From the shell, run this command to see where convert actually is:

which -a convert
TraaBBIT (talkcontribs)

[budrysl2@s53:: ~ ]:$ which -a convert


[budrysl2@s53:: ~ ]:$ (talkcontribs)

Adjust the path in $wgImageMagickConvertCommand to

$wgImageMagickConvertCommand = '/usr/local/bin/convert';
TraaBBIT (talkcontribs)

OK. Now it works. But still issue with SVG file: (talkcontribs)

The value of $wgSVGConverterPath is wrong. It needs to be the path without(!) /convert at the end.
