I installed the Patreon plugin on my Wordpress site and now I cannot access any pages inside my backend.
I get this error message:
Fatal error: Call to undefined function wp_add_privacy_policy_content() in /home4/j0d1tt/public_html/joditt.com/wp-content/plugins/patreon-connect/classes/patreon_wordpress.php on line 588
You can deactivate the existing plugin by renaming the plugin directory with ftp - ie, from patreon-connect to patreon-connect1. This will deactivate it.
Then you can update your WP, and then rename back the directory, and reactivate the plugin.
