 * Hi Raul,
 * thank you for this great plugin, I use it on various websites.
    This is the first
   time there have been problems.
 * When I try to clear everything this happens:
 *     ```
       Fatal error: Uncaught Error: Call to undefined function wpraiser_get_domain()
       in /home/public_html/wp-content/plugins/fast-velocity-minify/inc/common.php on line 377
       ```
   
 * Call stack:
 *  fvm_purge_varnish_cloudways()
    wp-content/plugins/fast-velocity-minify/inc/common.
   php:345 fvm_purge_others() wp-content/plugins/fast-velocity-minify/inc/common.
   php:132 fvm_process_cache_purge_request() wp-includes/class-wp-hook.php:303 WP_Hook::
   apply_filters() wp-includes/class-wp-hook.php:327 WP_Hook::do_action() wp-includes/
   plugin.php:470 do_action() wp-settings.php:509 require_once() wp-config.php:109
   require_once() wp-load.php:50 require_once() wp-admin/admin.php:34 require_once()
   wp-admin/update-core.php:10` `
 * I use **Cloudways** for hosting the website.
 * `wpraiser_get_domain()` is not defined. I googled this function, didn’t find 
   anything (?).
 * I’d be happy if you can help.

 * This is a bug specific of FVM on cloudways when we try to purge the cache.
    An
   update will follow today to fix this, sorry about that.
