 * I have recently updated all of the plugins on my website, updated to the latest
   WP and theme versions etc.
 * Now when I try to edit a page I get a fatal error. On checking the server error
   logs, this is revealed:
 *     ```
       [15-Nov-2021 21:52:40 UTC] PHP Fatal error: Uncaught Error: Call to a member function enqueue() on null in /home/trainonl/public_html/wp-content/plugins/sensei-certificates/classes/class-woothemes-sensei-certificates.php:1470

       ```
   
 * When I disable the certificate plugin, all works fine.
 * Please help 🙂

 * Hi [@davehep](https://wordpress.org/support/users/davehep/) !
 * I wasn’t able to reproduce the error with the latest versions of Sensei LMS, 
   WordPress, and Certificates.
 * Have you tried figuring out if Certificates are in conflict with some other plugin?
   You can do this by disabling everything except the Sensei LMS. If you then enable
   the certificates, does the error show up again?
