XF 1.2 Is Facebook Login Working?


Active member
Hi, I haven’t been able to make the Facebook login option to work.

Is this not working yet on 1.2 or am I doing something wrong?

Thank you.

I have followed what the link says.

When I try to log in I get:

Server Error try later.

Error Log:

XenForo_Exception: Invalid model 'XenForo_Model_UserExternal' specified - library/XenForo/Model.php:192

Sandbox mode in facebook app was on. I have just changed it to off. It says that It might take some time before it goes live.

Test Facebook integration says passed.

You should run the "File Health Check" under Tools. Looks like you're missing files.

This is what came out:


File does not contain expected contents.
