Hey, your answer seems correct and I have tried both and nothing has changed. I put debug mode on and I get this error, but I am unsure if it is related:

Warning: call_user_func_array() expects parameter 1 to be a valid callback, function 'upability_register_custom_menu' not found or invalid function name in /Users/danale/Downloads/mediafuel_workshop/wp-includes/class-wp-hook.php on line 298

I started this site using the underscores.me skeleton so my functions.php looks like this:

• as indicating support for post thumbnails. */
