Getting this every time I try to give feedback. Same error, same line, no matter who the feedback is for.

Code:
Warning: require_once([path]/includes/functions_wysiwyg.php) [function.require-once]: failed to open stream: No such file or directory in [path]/itrader_feedback.php on line 187

Fatal error:  require_once() [function.require]:  Failed opening required  '/home/buypoe/public_html/includes/functions_wysiwyg.php'  (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/buypoe/public_html/itrader_feedback.php on line 187
I am definitely one puzzled pirate.
