Thank You.
I did notice one thing on an old test site. If you are using SimplePortal < 1.0.1 (and since I did not formally release that, you probably are) then you MUST edit your Portal.subs.php file and change the following.
'query' => empty($allowed) ? '0=1' : 'FIND_IN_SET(%s, \'' . implode(',', $allowed) . '\')',
'query' => empty($allowed) ? '0=1' : 'FIND_IN_SET(%s, "' . implode(',', $allowed) . '")',
If you don't then you will get a hacking attempt error from the db controller, and probably a 500 error on your site.
