help! Post thanks error

[nbaphenom]

At the top of the page it says
Warning: Invalid argument supplied for foreach() in [path]/includes/functions_post_thanks.php on line 222

then it says vbulletin message .
Unable to add cookies, header already sent.
File: /homepages/5/d210752282/htdocs/includes/class_core.php
Line: 3243

Is it becuase the thread has gotten to big . Help this is important its stopping people from viewing the thread .
