The Facebook Canvas App allows members to view and post from within the Xenforo forum from within Facebook.A couple months ago I made a Facebook Canvas App for my Xenforo site and while it went over well with my members, I could not get it approved because I did not have SSL and I couldn't get it on my shared hosting at the time. Now that I am on a Managed VPS I have bought a SSL (just now, waiting for it to be activated) and am going to try to get my site approved and run Facebook Ads on it. Today I clicked on my app and it no longer works. I asked @0xym0r0n and hers no longer works either. I think Facebook has closed it off from people who aren't running SSL in order to cut down spam. If not, let me know. I know there is a vBulletin Facebook App officially created by vBulletin. I wonder how that's going. Mike Edge is creating a Facebook App that has been in development since 2011. His app will make use of Facebook's timeline and notifications. Me personally, I just want to get a basic canvas app running, no frills etc. Throw some ads up on there too.
