I apologize for the delay. However, just because there is no immediate response, please don't assume we won't help or aren't looking into the issue. Yesterday, I looked at the image you attached. Everything is correct there now. I also checked the HTML on the page and the issues I previously noted are not present anymore. I did try to login at that time, but there was a known Facebook bug occurring on many sites. The authentication didn't work, and, honestly, that was expected due to the glitch.
Additionally, if you just made changes, caches (Joomla, browser and even Facebook) can all contribute to some problems.
With that said, I just tested the Facebook Login on your site right now. My account was properly created, I was logged in, my profile was imported and my status in JomSocial was properly updated.
So, with that test, everything is working for me as I'd expect. Can you please test and let me know if you're still having issues? If so, please be very specific as to what the problem is as I can't recreate any problems right now, whereas I was able to before.
If, instead, you'd prefer a refund, there is a Refund Request link at the bottom of every page of this site. We'll gladly process it for you.
Thanks,
Alex
