Help! After I upgraded the Patreon plugin, all requests to my site are getting the error message “There has been a critical error on your website.”
I got this email:
Since WordPress 5.2 there is a built-in feature that detects when a plugin or theme causes a fatal error on your site, and notifies you with this automated email.
In this case, WordPress caught an error with one of your plugins, Patreon Wordpress.
An error of type E_ERROR was caused in line 2717 of the file /var/www/html/wp-content/plugins/patreon-connect/classes/patreon_wordpress.php. Error message: Call to undefined method Patreon_API::add_post_webhook()
