Hi,
More info on this, any news?
i'm having the same problem, i have 2 admin account, i set up an assignment and upload a file with the first account, then if i try to export to portfolio with my second admin account, then i'm getting the exact same error message, same goes for editingteacher-student pair, i have this problem in 3.8.3 as well as 3.10, i don't understand if it's a bug or it's inteded that you can export only your files (even tho i can download them no problem), i also tried to upload it with "public domain" same error.
Do you know anything that could help?
