 * That’s a small bug that is going to be fixed within the next version. In the 
   meantime, you can comment out the action call on line 151 in includes/hooks.php.
 * Change
    `add_action("load-plugins.php", "secondary_title_plugins_settings_link");`
 * into
    `// add_action("load-plugins.php", "secondary_title_plugins_settings_link");`
