Error when posting or previewing comments

Hi there, I'm getting this error what previewing or posting comments on my site:

warning: Invalid argument supplied for foreach() in /home/runic0/runicgamesfansite.com/torchlightmods/sites/all/modules/cck/content.module on line 1284.

I can still post the comments though, so it is really just an annoyance. Any clue on how to get rid of it?
