 * Unable to purge the cache since our database doesn’t use the default wordpress
   db prefix (“wp_”).
 * Error is:
 *     ```

 * I don’t use `wp_` for the database, I use `$wpdb->prefix` which is correct.
 * But for some reason the tables were not created on the update routine.
    Did you
   update directly from wp-admin, or did you perhaps upload the files separatly?
 * Can you disable and reenable the plugin and see if the error still shows up?
   
   Disabling and enabling the plugin, should trigger the tables creation.
 * Thanks

 * hi Raul, deactivating and re-enabling seemed to be the fix
 *     ```
       Success: FVM: All Caches are now cleared. (Tue, 29 Dec 2020 @ 12:10:19 UTC)
       Success: A cache purge request has been sent to <strong>WP Engine</strong>
       http_request_async curl error: Failed to connect to localhost port 80: Connection refused

 * Thanks for reporting.
 * As for the `http_request_async` error, we don’t use it on FVM, but it’s caused
   by the WP Engine plugin when we send a cache purge request to wp engine (likely
   you are not using their cdn).

 * You can ignore it until they fix it.
