Here is an updated answer below, please read comments below so you know what is happening... You will notice in my code comments which cases that I have tested and which cases I have not.. I don't have have plugins wpcf7, menu-image-options and revslider installed so it's hard for predict how these plugin edit screens work. Hopefully the logic of how I've presented my php code below might give you a better insight in how to accomplish your problem via a single function. If you still having problems, please get back to me. Updated code below... // add action to admin init to dedicate access add_action('admin_init', 'prevent_admin_access'); /** * if $user_id is not 1 then hide specific admin menu items * and prevent access to specific admin php pages * @return void */ function prevent_admin_access() { // global $user_ID var global $user_ID; // if $user_ID is not 1 if ($user_ID != 1) { // remove posts from wp admin menu remove_menu_page('edit.php'); // global $pagenow global $pagenow; // prevent admin access to specific php pages (tools, options-general, admin, edit) // switch case for $pagenow var switch ($pagenow) { case 'tools.php': // if $pagenow is tools.php die and exit message wp_die('You are not allowed to access the Tools page.'); break; case 'options-general.php': // if $pagenow is options-general.php die and exit message wp_die('You are not allowed to access the Options General page.'); break; case 'admin.php': // if $pagenow is admin.php... // get $page url var param from admin.php page $page = isset($_GET['page']) ? $_GET['page'] : false; // switch case $page switch ($page) { case 'wpcf7': // if $page is wpcf7 die and exit message wp_die('You are not allowed to access the Contact Form 7 page.'); break; case 'menu-image-options': // if $post_type is menu-image-options die and exit message wp_die('You are not allowed to access the Menu Image Options page.'); break; case 'revslider': // if $post_type is revslider die and exit message wp_die('You are not allowed to access the Revolution Slider page.'); break; default: // return if no $page match return; } // break out when done if ever necessary break; case 'edit.php': // if $pagenow is edit.php... // get $post_type url var param from edit.php page $post_type = isset($_GET['post_type']) ? $_GET['post_type'] : false; // switch case $post_type switch ($post_type) { case 'acf-field-group': // if $post_type is acf-field-group die and exit message wp_die('You are not allowed to access the ACF Field Group page.'); break; default: // return if no $post_type match return; } // break out when done if ever necessary break; default: // return if no $pagenow match return; } } } Anyway, hope this helps you out!

FIXED: My issue has been fixed by joshmoto. Here is fully working codes. Hide Admin menu items from users who are not Admininstrator of Wordpress: add_action( 'admin_init', 'hide_admin_menu_items' ); function hide_admin_menu_items() { $current_user = wp_get_current_user(); if ($current_user->ID != 1) { remove_menu_page('edit.php'); // Posts remove_menu_page('wpcf7'); // Contact Form 7 remove_menu_page('tools.php'); // Tools remove_menu_page('options-general.php'); // Settings remove_menu_page('edit.php?post_type=acf-field-group'); // ACF plugin remove_menu_page('menu-image-options'); // Menu image plugin remove_menu_page('revslider'); // Revslider plugin } } Prevent access to certain Admin pages if users are not Administrators: // add action to admin init to dedicate access add_action('admin_init', 'prevent_admin_access'); /** * if $user_id is not 1 then hide specific admin menu items * and prevent access to specific admin php pages * @return void */ function prevent_admin_access() { // global $user_ID var global $user_ID; // if $user_ID is not 1 if ($user_ID != 1) { // remove posts from wp admin menu remove_menu_page('edit.php'); // global $pagenow global $pagenow; // prevent admin access to specific php pages (tools, options-general, admin, edit) // switch case for $pagenow var switch ($pagenow) { case 'tools.php': // if $pagenow is tools.php die and exit message wp_die('You are not allowed to access the Tools page.'); break; case 'options-general.php': // if $pagenow is options-general.php die and exit message wp_die('You are not allowed to access the Options General page.'); break; case 'admin.php': // if $pagenow is admin.php... // get $page url var param from admin.php page $page = isset($_GET['page']) ? $_GET['page'] : false; // switch case $page switch ($page) { case 'wpcf7': // if $page is wpcf7 die and exit message wp_die('You are not allowed to access the Contact Form 7 page.'); break; case 'menu-image-options': // if $post_type is menu-image-options die and exit message wp_die('You are not allowed to access the Menu Image Options page.'); break; case 'revslider': // if $post_type is revslider die and exit message wp_die('You are not allowed to access the Revolution Slider page.'); break; default: // return if no $page match return; } // break out when done if ever necessary break; case 'edit.php': // if $pagenow is edit.php... // get $post_type url var param from edit.php page $post_type = isset($_GET['post_type']) ? $_GET['post_type'] : false; // switch case $post_type switch ($post_type) { case 'acf-field-group': // if $post_type is acf-field-group die and exit message wp_die('You are not allowed to access the ACF Field Group page.'); break; default: // return if no $post_type match return; } // break out when done if ever necessary break; default: // return if no $pagenow match return; } } } if you have more restricted Admin pages, just add more case ... Many thanks
