Fresh Install - "Login using Facebook" Refreshing Cycle

Russell,
Sorry to hear your running into issues. Absolutely, you should be able to use the social and profile plugins, so we'll help you to figure out what's wrong.

The issue is likely not caused by the social plugins/modules, so I'd recommend trying to re-enable those and trying again, just so we can narrow it down. Then, if it's still problematic, please let us know what profile plugins you are trying to enable, and if possible, enable them one at a time to see which specific one is the problem. Once you know, can you please let us know the following:
* What version of Joomla 1.6 are you using? The latest is 1.6.3, and that's where all of our testing has been performed, and what we recommend using.
* What version of the 3rd party extensions are you using for profile integration (what version of JomSocial, Community Builder, or Kunena are you using)?
* Finally, though you said you went through the guide, we have to make sure.. please verify the JFBConnect Authentication and JFBConnect User plugins are enabled.

Thanks, and we'll help you get to the bottom of it! By the way, we did look at your page, and there's nothing on the page itself that looks to be problematic.
