The issue is phpsuexec. The baby album site, wedding album site, entertainers portfolio and the photo
album will not work with servers with phpsuexec.
For some reason servers with phpsuexec will not recognize the admin user id and password on the sites
above. If you login to your hosting control panel and navigate to phpmyadmin you can see the admin user
and password. It just does not recognize it.
I can bypass the admin like I just did on your site.
You can password protect the admin directory from your cpanel.
