13484	Undefined Index when enabling Nav-Menus	etiger13		"In functions.php of my template file I added:

{{{
add_theme_support('nav-menus');
}}}


On the admin -> appearance -> Menus page I get at the top of the page:

{{{

On line 100 of /wp-includes/nav-menu.php a check should be made to see if the index exists. Function should be changed to the below:

{{{
function get_registered_nav_menus() {
	if ( isset($GLOBALS['_wp_registered_nav_menus']) )
		return $GLOBALS['_wp_registered_nav_menus'];
}
}}}

This is on PHP 5.3.1.

This is not a mission critical. It is a minor annoyance that occurs with PHP error reporting on and outputting to the screen"	defect (bug)	closed	normal	3.0	Menus	3.0	trivial	fixed
