Facebook Connect pop-up disapperance / login issue

[ckgb]

Hello,

Running 4.2.2

I suddenly started to have this problem with not being able to register/login through Facebook Connect. To clarify right away, I did not install any additional products or plugins. It was working and then it just stopped. To be sure I turned off all plugins/hooks. Deactivated products. It made no difference.

Checked on facebook dev section. All secrets/codes are up to date and valid. URL set up properly.


Here is what happens.Trying to register/login, pushing on Facebook connect button normal popup window comes up. I fill out information and push login on the Facebook Connect popup. Popup disappears and... nothing happens. New registration does not get started. Registered user can not login.

If I try to login through facebook connect while logged in through vbulletin, the browser goes into this infinite cycle. Below is the link it produces and te message Firefox spits out.

Firefox has detected that the server is redirecting the request for this address in a way that will never complete.

I would appreciate any ideas of what that might be.

Thank you very much.

Anybody knows what server port facebook Open Graph uses on the server where vbulletin is installed?
