I've got 2 php nuke pages on the same site. Page 1 doesn't have accounts so I can't login to it, page 2 I have an account on.

When I'm logged into my account on page 2, I get the following errors when trying to view page 1:

Warning: Invalid argument supplied for foreach() in /home/cyberpum/public_html/members/totalcoaching/includes/security.php on line 359

When I'm not logged into page 2 I can see page 1 just fine.

page 1 exists in a subdirectory of page 2.

Any ideas on how to fix this? So far I'm the only one who has seen the error on that site.
