[Resolved] Unable to register

Hello,

RESOLVED: Upon changing of skin.

UPDATE: One friend successfully registered but the rest still cannot register.

My friends are unable to register at my free forum which I created.

It keep stating 'Username is already taken' when there's only 2 user registered.

I'm using facebook skin.
