I went to Options>>Server Settings and Optimization Options>> and for 'Safe Mode Upload Enabled' option I selected 'yes'. I created a temp directory within my forum directory (not sure if that is secure or not) and I set permissions on it to 777. I then went to the option 'Safe Mode Temporary Directory' and I set the full path to my new tmp file there. I should look something like: /home/sitedirectory/public_html/forum/temp
Now when I try to set a custom avatar, I receive no problems or errors.
