Nothing Happens When I Click "Login With Facebook" Button

Griz,
You have another extension that's including and trying to initialize the Facebook Javascript API. They're also doing it in an incompatible way with OAuth2, which will be required by Facebook on October 1st. It looks to be your Gavick template that's doing it. Please disable the Facebook Login functionality of that template, and clear your Joomla caches.

Everything should work normally after that.

Thanks,
Alex

Steve,
The problems I'm seeing on your page are still there. I'll let you know exactly what they are, so hopefully, you can start narrowing down what's causing the problem. For both of these, just open the HTML that's being output to the page with whatever browser you're using.
1) If you search for "all.js" in the code, you'll see a line in the header of the page that ends with #xfbml=1 . That insertion of the Facebook Javascript library is not from JFBConnect, and is likely part of the problem. You should try to disable any sort of extensions/templates that may have Facebook integration to remove that.
2) If you search for "FB.init", you'll see JFBConnect's code at the top of the page. At the bottom is the insertion from Gavick (which includes the appID: ' ' line, which is bad since no AppID is specified). This will need to be removed as well, which should be in the template's parameters.

Since browsers load things in different order, with multiple inclusions of similar code, you'll see different results with different browsers. In all cases though, with the problems above, things won't work. Once those two things are fixed, you should be good to go.

Hope that helps,
Alex

Griz,
You don't need to disable all Facebook integration from other extensions. But sometimes, others do conflict or try to overlap with what JFBConnect does. JomSocial is a perfect example. You can't have 2 extensions trying to manager user registrations through Facebook, and it should be disabled in JomSocial. For our quick integration guide with JomSocial, see:
www.sourcecoast.com/jfbconnect/docs/thir...ration-for-jomsocial

The #xfbml=1 and big chunk of code at the bottom are still the issues on your site. I believe these are coming from your template, and in there, you'll need to disable any Facebook integration. I don't know your template, or Gavick's templates real well, but I know in the past, other users have been able to disable the Facebook/Social integration in them. Another suggestion would be to contact Gavick to get more information on how to turn off their Facebook inclusion.

Malta,
I just looked at your site, and didn't run into any issues registering or subsequently logging in. Looking at the HTML on your page, there's nothing I see wrong with your page. Can you give more information about how your testing (browser, OS, etc), if the issues happen on specific pages, or any other information. Also, please try clearing your browser cache, Joomla's cache, and possibly even on another computer, if possible, to see if things improve (or get worse).

Thanks,
Alex
