Server issue Trying to set a profile banner causes an unknown error

Affected version


Well-known member
Trying to set a profile banner causes an unknown error. Happened 2 times. First I got error, then I could successfully set 3-4 banners (changed them). Then wanted to test again and got problem again. The error log from the console is included below.


From the console:
