I upgraded an old version of zencart to the newest and everything is working fine except when I try to delete old customers I get this error:

Warning: reset() [function.reset]: Passed variable is not an array or object in /home/cowtownw/public_html/admin/includes/classes/object_info.php on line 29

Warning: Variable passed to each() is not an array or object in /home/cowtownw/public_html/admin/includes/classes/object_info.php on line 30

The site functions fine and I guess I can just leave the old customers, I was just wanting to see if anyone could tell me if this was bad and something else could be wrong, or what the deal is.

Thanks
