Thread:Project:Support desk/Urgent: Thumbnail not working in MediaWiki 1.19/reply (10)

Good to hear that you got it to work :)

I wonder about this as well.

It will be fixed in version 1.20 - I don't know if the developers will add the fix also to the 1.19 version. If I got it right this issue appears only if you use shared hosting (I do).
