A teacher reported to me that she is unable to delete a simple resource in her course (a PDF). When she tries to delete the file she first gets the standard "Do you really want to delete the file..." but when she clicks Yes, an error pops up that says "Unknown Error." As the admin, I also get the same response when trying to delete the file. Actually, the file at first disappears from the page but when the page is refreshed it is still there.
We recently upgraded to Moodle 3.1+, I'm wondering if this is a bug in this recent version of Moodle.
Any advice you can give me regarding this problem would be greatly appreciated!
