I am getting this error now when i try to login to joomla with the facebook login button. - Can it be related to ipv6 ?
Facebook API Error: Failed to connect to 2a03:2880:2110:3f01:face:b00c:0:1: Network is unreachable

The address above is still definitely an IPv6 address (2a03:2880:2110:3f01:face:b00c:0:1), and the message is definitely indicating that your server can't communicate over IPv6. This is actually a common mis-configuration issue: the DNS on your server is IPv6 enabled, but the underlying network can't communicate that way. So, IPv6 addresses are looked up but can't be used.

The error page you're seeing is likely caused by the same issue. JFBConnect is having problems communicating with Facebook for required operations during login and so therefore is erroring out. If you go into Global Configuration and turn off GZip and set Error Reporting to "Maximum", you may get a more detailed error message that will help debug things further.

Hope that helps. We're working on a bug-fix release for JFBConnect (due out early next week) that will have a fallback for IPv6 servers that are configured incorrectly. The code comes from Facebook on how to do this. In general though, it will cause slower logins since it will first be attempted over IPv6, have to fail, and then revert to IPv4. It will work, but it's recommended to fix the underlying problem if possible.

If you'd like that code now to try, we can send it. We haven't tested it at all yet, but it may help.

Thanks,
Alex

Can you go into Global Configuration and turn off GZip and set Error Reporting to "Maximum", you may get a more detailed error message that will help debug things further. Additionally, please try disabling all JFBC Profile plugins you have enabled. From looking at your site, I'd guess you should only have the JomSocial profile plugin enabled. If you have others enabled, especially for extensions you don't have installed, disable those.

Sounds like we're on the right track though now that IPv6 is disabled.

Thanks,
Alex

Can you go to the JFBConnect Overview page and check the version of your JomSocial profile plugin? I think yours is out of date and simply needs to be updated.

If it's showing that you have the most recent version installed, let us know and we'll go from there.

Thanks,
Alex
