FB login not working for new users

That page is loading another site within an iFrame that is only an IP address. Facebook doesn't like working over IPs and not domain names. Generally, IP addresses are a lot more shady than real domain-based websites.

I'd recommend switching your site to not use an IP address frame.

The other things you can check are:
* Your app is not in Sandbox Mode
* Your app domain and Site URL are correct for the IP you're using. Again though, you don't really have an 'App domain' in this case, which is likely the problem. These settings should have been configured properly through Autotune. Without a valid subscription, you'll need to edit them manually in the Facebook Developer Area.

I hope that helps narrow some things down. The issue is not due to your subscription expiring. There is nothing in our login code that checks if your subscription is active to intentionally make things fail.

Your site is still loading a IP address in a frame. As mentioned above, I believe that's the main culprit and is what needs to be fixed. The other suggestions were ideas that may work around that issue, but if not, the solution is to load your content from a real domain.

I just tried to register, and I got an error "This email is already registered.". It's likely you don't have the Automatically Connect Users by Email address enabled and I already have an account on the site for some reason. In any case, it seems like it did work for me as it's getting my email from my profile. I didn't see the access token error you mention.

I still think using a real domain may help. If not, please test with different users on different computers and let me know if it happens for all Facebook users, or just some. Also, please delete my account on your site or enable the setting I mentioned above and I can test more.

Thanks,

If you update the settings in your App, that's all that matters. JFBConnect shows whatever was last fetched when using Autotune in your overview page, so that won't update until you run Autotune again.

Regarding the actual update, were you still loading your website in an iFrame that loaded an IP Address? If so, that wouldn't change anything. You need to change how you're loading the site and I'd recommend removing the iFrame altogether. If you can't do that, at least have the iFrame load a domain-based page and not an IP.

Thanks,
