I use Wp 4.3 with Avada Theme 126.96.36.199. Avada support gives me a hint to solve a problem: I have a big problem with my menu items in Power Menu plugin. A lot are disappeared when updating (add) a menu item. Also the Manage Location tab settings are not selected after an update. When I do select them again, the complete menu is gone from the site.
From Avada support I get this solution:
To make this work I edited the priority numbers on the action calls that the plugin makes. In particular the power-menus/power-menus.php:
add_action('wp_update_nav_menu_item', 'power_menus_custom_nav_update', 30, 5); add_action('admin_init', 'power_menus_secure_page_meta_box'); add_action('init', 'power_menus_output_buffer', 0); //add_action('admin_enqueue_scripts', 'power_menus_admin_enqueue_scripts');
/* Filters */
add_filter('wp_edit_nav_menu_walker', 'power_menus_nav_walker', 30, 5); add_filter('wp_setup_nav_menu_item', 'power_menus_custom_nav_item'); add_filter('wp_nav_menu_objects', 'power_menus_main_navigation_links', 30, 5);
Notice the numbers are 30, 5. This is higher than previously set, which means the plugin takes priority over the theme for menu item options.
WordPress has a limitation on the number of options added to the menus. So it cannot have both from the theme and from the plugin.
This just works a few days. Now not more. I have tried several combinations without success.
Has someone an idea how to solve this. From the developers WP Idiots, I do not get a reply.
