			stripos($_SERVER['REQUEST_URI'],'/wp-admin/') !== false
			&&

			stripos($_SERVER['REQUEST_URI'],'async-upload.php') == false
			&&
			// Allow calls to admin-ajax.php
			stripos($_SERVER['REQUEST_URI'],'admin-ajax.php') == false
		) {
				// Does the current user fail the required capability level?

                        exit;
                }
			}
        }
        add_action('admin_init', 'restrict_access_admin_panel', 1);
