Hi, this site is dropping the wp-admin page so the client can’t log-in – a debug plug in is showing the following error, can you advise please?
wp-includes/class-wp-user.php:734 – has_cap was called with an argument that is deprecated since version 2.0.0! Usage of user levels is deprecated. Use capabilities instead.
require_once(‘wp-admin/admin-header.php’), require(‘wp-admin/menu-header.php’), _wp_menu_output, current_user_can, WP_User->has_cap, _deprecated_argument
