Hello everybody!
We faced with a problem, which started to occur sometimes (but not in every case). The thing is that when a student tries to upload a file within assignment he sees the system notification and cannot upload a file. It's something like that "It is impossible to create catalogs in a local file area. Check permissions in catalog dataroot" (it's my own translation from Russian Moodle version, probably it sounds a little bit different in English, but I hope you grab the meaning).
Does anybody know what's the cause of a problem?
