Facebook App shows "Nothing to display."

[studify]

Hey,
I've already opened a Support Ticket 10h ago, but no one replied.

Unfortunatly my Facebook-App does not work for me, it only shows "Nothing to display." and Login/Registration says "Unable to complete registration at this time, please try again later.". I've followed the (very poor) Instructions PDF several times, but couldn't find any wrong setting etc. I've also commented out

$this->vurl->set_option(VURL_FOLLOWLOCATION, true);
$this->vurl->set_option(VURL_MAXREDIRS, 1); 

as mentioned as a solution in other threads, but it didn't work.

My App: https://apps.facebook.com/studify-boards
Files Directory: https://apps.studify.at/facebook/
Forum URL: https://boards.studify.at/

My Fb-Dev-Settings:


SSL certificate is of course installed and Fb Connect is set up correctly and working!

Please help me!

All the best,
Alexander

I see that this is working now. I'm having the same issue. What was the fix?

Is your forum running in a sub-domain and your app files in a different one?

[grayloon]

Nope.

In the Facebook app images, your Forum URL should be what you just posted is the link to your forums, and your two canvas URLs should be what you just posted is the link to your app.

edit: OK, I just saw you're not the original poster and this is why we ask users to start their own thread with their own details. Please start your own thread and post images like the original poster did here.
