White page when trying to register with Facebook

But when i clicked it I got a small popup, but then nothing. The popup never loads and remain white.

The popup itself from Facebook remains white, or the original page from your site turns white?

The best recommendations I can make are:
* Turn on the "Enable Debug Mode" setting in JFBConnect and see if any additional errors show
* If your site's page turns white, set "Error Reporting" to 'Maximum' in the Joomla -> Global Configuration area and see if an error shows

Let me know if those help. If not, please post, or Private Message, a URL where we can see the issue.

Thanks,
Alex

I'm very sorry for the delay. I just had a chance to look into your issue. The problem looks to be from the following file:
templates/yoo_everest/warp/js/social.js

That file is re-including the older version of the Facebook Javascript library and *I believe* is causing a conflict with the login button, preventing it from working. Normally, I'd test by adding ?template=atomic to the URL, which will load the default Joomla template. That's just making your page white, so I couldn't test if the page works without that file being loaded.

I'd recommend:
* Switching the template quickly and see if the Login button works then
* If so, determine how to disable the loading of that social.js file from the template your using to see if that works.

I hope that helps get you going, but if not, please let us know and we'll gladly help investigate further.

Thanks,
Alex

Now, if I'm not logged in to Facebook, and try to use Facebook to login to your site, I'm seeing the authentication popup. It's asking for my email and password, as expected. However, after that, the box still turns white.

Can you verify that you've enabled your Facebook application for a public use? That setting is in the Facebook Developer area in the "Status and Review" section. Make sure the "Do you want to make this app and all its live features available to the general public?" is "Yes".

Let me know how that goes,
Alex
