Ultimate Facebook plugin conflicts with Profile Builder Pro

Hi,

The "Login with Facebook" feature of the Ultimate Facebook plugin does not work when I also have the Profile Builder Pro plugin running.

I'm using Ultimate Facebook to place a "Login with Facebook" button on my website. When I click that button, the little flashing blue rectangles start twinkling as if its going to sign me in, but then the blue "Login with Facebook" button just comes right back and I am not signed in. When I disable Profile Building Pro, the Ultimate Facebook plugin seems to work properly.

I am using Profile Builder Pro to add some extra profile fields and provide non-admin users with a front-end view of their Profile.

Can you tell me how I can get these plugins to play nice together? Or, do you have a plugin that is compatible with Ultimate Facebook that I could use instead of Profile Builder Pro to achieve the same results?

Thanks,
Melissa
