Hello,
Try to add the following PHP code snippet to the child theme functions.php file to do this
if ( ! function_exists( 'change_capabilities_of_cms_block' ) ) {
/**
* Grant access to html blocks only to users with administrator rights.
*
* @param array $args Array of arguments for registering a post type.
* See the register_post_type() function for accepted arguments.
* @param string $post_type Post type key.
*
* @return array
*/
function change_capabilities_of_cms_block( $args, $post_type ) {
if ( 'cms_block' !== $post_type ) {
return $args;
}
$args['capabilities'] = array(
'publish_posts' => 'manage_options',
'edit_posts' => 'manage_options',
'edit_others_posts' => 'manage_options',
'delete_posts' => 'manage_options',
'delete_others_posts' => 'manage_options',
'read_private_posts' => 'manage_options',
'edit_post' => 'manage_options',
'delete_post' => 'manage_options',
'read_post' => 'manage_options',
);
return $args;
}
add_filter( 'register_post_type_args', 'change_capabilities_of_cms_block', 10, 2 );
}
Kind Regards
