Are you seeing an error like this below at your website? If so, either open a ticket with us OR log in to your cPanel and choose multiphp manager and switch to PHP 7.4. Did that fix your issue? If so, it means your site (likely Wordpress) is not updated to use the newest secure version. The server updates automatically to use newer coding versions when prior ones become 'deprecated' or 'end-of-life.'
Service Unavailable
The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.
Additionally, a 503 Service Unavailable error was encountered while trying to use an ErrorDocument to handle the request.
