The RFacebook Debug Panel

Have you ever been debugging and just can't figure out what is wrong that one page? Sometimes Rails backtraces can't tell you the real reason behind your problems. There is a better way - look no further than the RFacebook Debug Panel:

The panel shows up when you use render_with_facebook_debug_panel in your controller actions. Its perfect for those bugs that are being caused by a simple misconfiguration.

This panel also shows up automatically in the Canvas when an exception occurrs. It will appear above the backtrace to give you a better idea of what the problem might be.
