Fatal error

Hi,

I have this issue on a local installation under Laragon.

Fatal error: Uncaught Error: Call to undefined function menu_page_url() in D:\laragon\www\zou\wp-content\plugins\gp-shortcuts\includes\classes\class-gp-shorcuts.php:55 Stack trace: #0 D:\laragon\www\zou\wp-includes\class-wp-hook.php(308): GP_Shortcuts::register_bar_menu(Object(WP_Admin_Bar)) #1 D:\laragon\www\zou\wp-includes\class-wp-hook.php(332): WP_Hook->apply_filters(NULL, Array) #2 D:\laragon\www\zou\wp-includes\plugin.php(565): WP_Hook->do_action(Array) #3 D:\laragon\www\zou\wp-includes\admin-bar.php(95): do_action_ref_array('admin_bar_menu', Array) #4 D:\laragon\www\zou\wp-includes\class-wp-hook.php(308): wp_admin_bar_render('') #5 D:\laragon\www\zou\wp-includes\class-wp-hook.php(332): WP_Hook->apply_filters('', Array) #6 D:\laragon\www\zou\wp-includes\plugin.php(517): WP_Hook->do_action(Array) #7 D:\laragon\www\zou\wp-content\themes\generatepress\header.php(26): do_action('wp_body_open') #8 D:\laragon\www\zou\wp-includes\template.php(783): require_once('D:\\laragon\\www\\...') #9 D:\laragon\www\zou\wp-includes\template.php(718): load_template('D:\\laragon\\www\\...', true, Array) #10 D:\laragon\www\zou\wp-includes\general-template.php(48): locate_template(Array, true, true, Array) #11 D:\laragon\www\zou\wp-content\themes\generatepress\index.php(18): get_header() #12 D:\laragon\www\zou\wp-includes\template-loader.php(106): include('D:\\laragon\\www\\...') #13 D:\laragon\www\zou\wp-blog-header.php(19): require_once('D:\\laragon\\www\\...') #14 D:\laragon\www\zou\index.php(17): require('D:\\laragon\\www\\...') #15 {main} thrown in D:\laragon\www\zou\wp-content\plugins\gp-shortcuts\includes\classes\class-gp-shorcuts.php on line 55
