Yesterday, my code was working (uploading XML), and my canvas was displaying properly. Today I get the "Not a valid app canvas" message. My code is still the same, I can see it in the textarea. What's causing this to happen, and how can I fix it?

Thanks,

I figured it out. Somehow my canvas page Enabled checkbox was unchecked. Pretty sure I didn't uncheck it. Oh well.

This frikkin forum is like talking to myself.

I just got that message and had to refresh/validate my xml
