 * Hi [@quantazelle](https://wordpress.org/support/users/quantazelle/),
 * Thanks for choosing WP Maintenance Mode!
 * None of those errors point to WP Maintenance Mode. Most of them are related to
   WordPress itself and two of them point to the Sensei LMS plugin. You could try
   to back up your site and check for plugin conflicts. If this doesn’t help, you
   could try to make a fresh installation of WordPress.
 * Have a nice day!
