WordPress is screwing up my Facebook Connect Authentication

I’ve got a test site that authenticates fine using facebook connect. It takes a custom field when the user registers.

Now, ive ported this as a WordPress theme several times and had other people to do it and it will not work at all.

It refuses to load the Login button without having some Javascript right before it. Then it will always show the Login button whether im logged in or not, however clicking it will just make you type in your password and will then load Facebook in a popup.

It currently takes the users data when the register (Facebook ID & Custom Field) and stores it into a database which works fine.

The non-wordpress version is https://students.so/wp/wp-content/themes/studentsso/app_name/

The wordpress version is https://www.students.so/wp/

If you need to remove yourself from the app its https://www.facebook.com/apps/application.php?id=201858056521105

If anyone could shed any light on this then please help.
