I'm not seeing the Javascript errors in the console that you mention. When I try to login with Facebook, I'm seeing the following message:
Error - The specified feature has been temporarily disabled for this application
That message is only shown if I am logged out of Facebook and have to enter my credentials into the popup. If I'm already logged in, the box just goes away and nothing happens. Both are strange results.
The only thing I can guess is that you have some restrictions placed on your Facebook application. Can you go to the
Facebook Developer Area
and check that:
* Sandbox Mode is Disabled
* There are no geographic restrictions on your app
* There are no age limits on your app
* There are no other restrictions (IP Whitelist, etc)
Autotune should configure everything pretty well, but if you modified some settings int he app, it could have caused a problem.
Again, something strange is happening since you're seeing different Javascript errors. The errors I see are:
Uncaught TypeError: Property '$' of object [object Object] is not a function mega.js:33
Uncaught TypeError: Property '$' of object [object Object] is not a function (index):178
Those may be causing some issues with the Facebook or JFBConnect Javascript, but I really don't think that's the cause.
Let me know if that helps get you started or what you find in your app and we'll gladly keep help investigating.
Thanks,
Alex
