GeneratePress bug in navigation.php when used with CoursePress plugin from WPMU

I found a fix for the bug at line 213 in navigation.php that solves this and simply wanted to share it.

The modified code is:

	if ( in_array( $args->theme_location, apply_filters( 'generate_menu_arrow_theme_locations', $theme_locations ) ) ) {
		if(null != $item->classes) {
			foreach ( $item->classes as $value ) {
				if ( 'menu-item-has-children' === $value  ) {
					$title = $title . '<span role="button" class="dropdown-menu-toggle" aria-expanded="false"></span>';
				}
			}
		}
	}

The original code was:

	if ( in_array( $args->theme_location, apply_filters( 'generate_menu_arrow_theme_locations', $theme_locations ) ) ) {
		foreach ( $item->classes as $value ) {
			if ( 'menu-item-has-children' === $value  ) {
				$title = $title . '<span role="button" class="dropdown-menu-toggle" aria-expanded="false"></span>';
			}
		}
	}

Just thought that this might be useful for others too.
