I’m encountering intermittent errors when uploading images. When I try to upload images, about 90% of the time it’s giving me what I presume to be the standard ImageMagick error (see below), and when I run the ImageMagick path test, it fails. This has impacted new installs as well as older ones that have been working for 1.5+ years. I’ve contacted the sysadmin about this, and they have said nothing has changed.
Are there any common issues (either with Omeka or with the server) that could cause this? Is there any further information I could relay to the sysadmin to help with this?
When you upload an image:
Omeka_File_Derivative_Exception
