Thread:Talk:MediaWiki 1.19/Thumbnails didn't work since Update to 1.19/reply (14)

Some more info that I guess is relevant: I have another, older mediawiki installation running on the same server, where file uploads work fine. That is MW 1.15.1 though. I also just realized that php safe mode is enabled on our server. Is that a likely cause for trouble?

CORRECTION: I just realized that, although file uploading has worked fine for the purposes I have had till now, *thumbnailing* does not seem to work in any of the MW installations on our server. (Haven't had the need for thumbnailing until now.) So I guess this issue is not related strictly to version 19 of MW, but is a general issue with either MW or our server. Sorry about that.

Still, if anyone has any idea about how to diagnose this problem, I'd be thankful!
