Thread:Project:Support desk/Problem with thumbnails of images transcluded from WikimediaCommons

URL: http://kudlok.pl MediaWiki version: 1.20.5 PHP: 5.3.8 (cgi-fcgi) MySql: 5.5.28 Server: openSUSE 12.1 The wiki is installed in a root folder

I have the following problem with my wiki: I've just upgraded my wiki from 1.16.5 to 1.20.5 and also moved it from a shared hosting to a virtual server (OpenSUSE 12.1). Everything works fine except for thumbnails of images transcluded from WikiemdiaCommons (InstantCommons enabled).

Precisely: thumbnails of pictures transcluded from Commons are visible only in a "show preview" mode but when I save the page they disappear and only blue links can be seen. When I click on the link the full size image appears (as it should). What's more, when I re-edit such pages and click "show preview", the thumbnails of the images transcluded from Commons are again visible but when I save the page they disappear again.

You can see that invisible thumbnails here: http://kudlok.pl/Rozstaw_szyn#Rozstawy_w.C4.85skotorowe

When I go directly to a thumbnail, i.e.:

http://kudlok.pl/thumb.php?f=Waldenburgbahn.jpg&width=120

I get the following error message:

Error generating thumbnail

The source file for the specified thumbnail does not exist.

But the thumbnail exists in the images/thumb catalogue:

http://kudlok.pl/images/thumb/6/68/Waldenburgerbahn.jpg/120px-Waldenburgerbahn.jpg

It doesn't matter if I add  to LocalSettings.php or not. Nothing changes.

Also, thumbnails of the pictures uploaded to my wiki don't cause any problems and are visible:

and thumbs are generated properly:

I've spent a lot of time trying to resolve the problem and I haven't managed to. Does anyone have any idea what's wrong? I'd be grateful for any tips. Thanx in advance for your help.
