Love the framework, been using it for a long time.
Anyways I'm getting a Fatal error: Call to undefined function submit_button()
It shows on group-admin pages, profile-edit etc. I looked at the compatibility.php file that houses the function and couldn't see anything wrong off the bat with the version checker work around you explain in the file but I must admit my expertise stops when it comes to understand the call stack. compatibility.php is loading correctly through the framework init.php as well. I was able to fix the issue by providing the button without the function call but obviously it would be beneficial to have it. Oh and this is something straight out of the box with WordPress 3.1.2 latest framework release and the only plugin installed is buddypress.
