Recently we upgraded via the one click installer to the new version on Mediawiki that DH provides and all was well.
A couple of days ago we were moved to a new server and since that point the software cannot create any thumbnails for new images uploaded to the wiki.
Previous uploads continue to work, but otherwise new uploads needing a thumbnail don't.
I have put in a ticket, but the response was to point us in the direction of log errors that have absolutely nothing to do with the issue.
It appears that the images are uploaded correctly, and clicking on a full size image will make them appear as they should look.
Does anyone have any experience in this issue and how to solve it? Is it possible that the location of Imagemagick has changed or that a newer version is needed for Mediawiki than is available? Perhaps this is a bug in Mediawiki, but if it is, how do you go about fixing it?
Thank you for any thoughts!
