• Your plugin is causing this error:
    “has_cap was called with an argument that is deprecated since version 2.0! Usage of user levels by plugins and themes is deprecated. Use roles and capabilities instead.”
    FROM wp-includes/functions.php:3006
    Here is the call stack:
    WP_User->has_cap()
    current_user_can()
    add_submenu_page()
    add_options_page()
    wpts_settings()
    do_action(‘admin_menu’)

    Thought you should know. Found the error with Query Monitor.
