How to solve the problem of fatal errors when customizing themes and backgrounds in WordPress? Many novices are not very clear about this. In order to help you solve this problem, the following editor will explain it in detail. People with this need can come and learn. I hope you can gain something.

If you encounter a fatal error when opening the WordPress customization and background menu, something like this:

Fatal error: Uncaught Exception: Supplied nav_menu_item value missing property: description in xxxxxxxxxx/wp-includes/customize/class-wp-customize-nav-menu-item-setting.php:183

You can try to solve it with the following code.

A fatal error resolution was encountered when trying to customize the theme and background of WordPress

Add the code to the current theme function template functions.php:

Add_filter ('wp_get_nav_menu_items',' my_wp_get_nav_menu_items', 10, 3); function my_wp_get_nav_menu_items ($items, $menu, $args) {foreach ($items as $key = > $item) $items [$key]-> description ='; return $items;}

After that, the error of opening the custom theme menu again disappears, but the code must remain in the theme, and the problem persists after removal.

Another solution is to delete all the menus built in the background, which can completely solve the problem, and then recreate the menu. I have not tried this method, there are similar problems of children's shoes can try, there is no loss.
