Yahoon23 - that's a bug in the file, I forgot to add the ".TABLE_PREFIX." to the part after the WHERE clause...
Find line ~200 under the -> //Various View Types For Feedback Display
under the switch case 4: -> //Feedback Left for Others
WHERE user_rate_trade.userid
to
WHERE ".TABLE_PREFIX."user_rate_trade.userid
I thought I got all the SQL table prefixes, but I guess I missed one...
