http 500 error with facebook login

The SSL cert error your getting isn't with the SSL cert on your site, it's with your server validating the cert that comes back from Facebook.

You should enable the "Disable SSL Certificate Validation" setting in the Facebook API tab of configuration. That setting is actually named poorly, as it's from the previous 3.x series. In 4.x, enabling that setting will simply use a file that we distribute with JFBConnect which will validate the certificate from Facebook.

Try it with that setting enabled, and you shouldn't run into any issues (or bad consequences). If you still run into issues, just let us know!

If you're getting a 500 error, it's likely that there was a PHP error occurring. If it's pretty repeatable, can you change the following settings in the global configuration area:
* Disable GZip compression (if enabled)
* Set error reporting to "Maximum"

Then, the 500 error will hopefully show any PHP errors that are occurring, which will help us narrow down the problem.

Thanks,

Oliverious,
Sorry for the delay in getting back to you, and thank you so much for the review! We really appreciate it!

As for the PHP error you should see, it likely will be in the PHP log file, but I was mainly talking about seeing it on the site itself.

I just looked at the homepage on your site, and am seeing some oddities. Mainly, in the head section, our JFBConnect javascript code is being included twice. While that really shouldn't cause a problem, it's an indicator that something is going a little strange. Can you try the following things, which I think will likely fix your problem.. but not sure which one will do it:
* Disable caching on your site - Both in the "Global Configuration" area and the "System - Cache" plugin, if you have it enabled.
* Re-arrange the JFBCSystem plugin to be ordered first (lowest number) or last (highest number).

Test in both cases above, and let us know your results. If it's the caching, don't worry, we'll be able to help you re-enable it.. we just need to narrow down the conflict first.

Thanks,
Alex

I'm assuming you're using Joomla 1.7. If so, can you tell me what setting the Global Caching was enabled to? There's a few of like optimized, passive, etc.

You shouldn't really be getting the "We were unable to retrieve.." message either, so while things may have improved, something's still not right.

Would you have a problem sending me a set of admin credentials so we can look at the configuration of things on your site? You can private message them to me by clicking the arrow under my picture (<----) and hitting the mail icon. If you don't want to do that, I understand, we'll gladly continue trying to narrow things down however we can.

Thanks,
Alex

Oliverius,
Thanks for all your patience and help with getting access to your site.

I made a modification to JFBConnect to actually disable SSL verification instead of what we were trying to do before. I'm not sure why your site doesn't like the bundled certificate we supply, but it doesn't. The change I made should get you by for now without any problems, but if you run into anything, let us know.

We'll investigate possible solutions for our next release. Hopefully for now, this will get you going though.

Thanks again,
Alex
