Problem when someone posts.

Hi,

At the moment, I can't actually check what's on line 1063.
The error is very odd though, as myplaza_general.php doesn't even have any effect on posting.
Anyways, ignoring that, there's only a few possible problems.  I presume you haven't changed any templates?  If not, try reuploading /inc/myplaza/myplaza_general.php and see if that helps.
