Hi – I have looked at this error and will try and provide as much info as possible. I have tested this with my own facebook login, and 4 others (friends). My site is open to the public yet.
From what I can see the facebook login page is redirecting back to my site many times. The code that creates the new user seems to take a few seconds and while the user is being created – the same function is being called many times. Until WP finally creates the user and then facebook stop redirecting and the user goes to my site.
I can see in teh User list that many users have been created.
On safari I get an error as it does not like the redirects. In the post meta table I can see that the users are created every 2 seconds!
I guess I could add some debug statements. But just wanted some advice and see if you had any idea about what is happening. I though of adding the username to a session so that the New user will only be created 1.
