Cannot Log In Using Google Button (but FB Button works fine)

I just tried to authenticate and it does seem like the login is working, but JFBConnect isn't processing it properly. Can you try the following to see if they fix the issue or help narrow down a cause:
* Disable SEF URLs on your site -- temporarily, just to see if the authentication works.
* In JFBConnect -> Configuration, set "Debug Mode" to "On". A message may appear after you're returned to your site from Google explaining why authentication is failing.

Hopefully, the above will help us determine where things are going wrong.

Thanks,
Alex

I'm glad to hear that 8.0.1 fixed the issue on one of your sites. I'm unsure what's happening on the other site, but I'd double-check your settings in JFBConnect and your Google application.

On the site that doesn't work still, please make sure you've tried the debug and SEF steps I mentioned above. In addition, please disable any caching you have enabled.. either in Joomla or 3rd party caching extensions.

Additionally, try:
* If you have any social network extensions installed, which may be in your template or other places, try disabling those as well.
* Re-order the JFBCSystem plugin to be the first in the System group. That can help it execute before any other plugins that may try to recognize the Google authentication.

Let us know if that helps or not and we'll help however we can if not.

Thanks,
Alex
