SClogin facebook auth does not complete.

Hi..

Ive done a lot of searching on youre page, but i cant seem to find the answer to my troubles.

SClogin is working on my site physique.dk - Login in the top right corner ( as text - the template overrides the style of the login button )

When choosing login with facebook - The facebook iframe is popping up, asking the user for typing in their FB credentials - Afterwards, the popup just goes BLANK.

with the following code :

www.facebook.com/dialog/oauth?redirect_u...ash=AebWN2_gIptuQ1MQ

The facebook app has a redirect ling set to the startpage physique.dk

Ive tried enabling SSL bypass in the JFConnect applikation - Does not Work.
Tried enabeling / disabeling a lot of modules / components - and made shure the template facebook integration was turned off - and not interfering with the app.

Why does it not redirect back, and accept the login ?

Picture attached.

Just an info.

If i have been logged into facebook on the computer with MY id - Where the facebook app is registered - The auth just flyes through.

But none other users.

I have similar issue.
