Fatal Errors in settings page

Hi I was hoping you guys could help me? I’m using the latest version of the plugin using the latest version of WP and I get this error.

Fatal error: Uncaught Error: Call to undefined function wp_enqueue_code_editor() in /httpdocs/wp-content/plugins/megamenu/classes/settings.class.php:3968 Stack trace: #0 /httpdocs/wp-includes/class-wp-hook.php(298): Mega_Menu_Settings->enqueue_scripts('toplevel_page_m...') #1 /httpdocs/wp-includes/class-wp-hook.php(323): WP_Hook->apply_filters('', Array) #2 /httpdocs/wp-includes/plugin.php(453): WP_Hook->do_action(Array) #3 /httpdocs/wp-content/plugins/megamenu/megamenu.php(154): do_action('megamenu_admin_...', 'toplevel_page_m...') #4 /httpdocs/wp-includes/class-wp-hook.php(298): Mega_Menu->admin_enqueue_scripts('toplevel_page_m...') #5 /httpdocs/wp-includes/class-wp-hook.php(323): WP_Hook->apply_filters(NULL, Array) #6 /httpdocs/ in /httpdocs/wp-content/plugins/megamenu/classes/settings.class.php on line 3968
