My menu doesn’t save custom fields

If you have numerous menu items added to your navigation via Appearance -> Menus, sometimes, the last items may be not saved correctly. Especially custom fields like design, icon name, and the label can’t be handled properly. In most cases, this issue is connected to the PHP max input vars limit parameter in your web server configuration. You can check the current value for this parameter in your Dashboard -> WooCommerce -> System status. Usually, this parameter is not allowed to be changed on shared hostings, so you will need to contact your server providers and ask to increase this limit. The recommended value for this is 10000
