Hello @bonsius,
The reported error indicates that there is an issue with the request you’re making, and the server responded with a status code of 400, which typically means a bad request.
The most common reasons for that are:
Permissions: Verify that the account making the request has the necessary permissions to enable Memcached. Insufficient permissions can lead to such errors.
Network Issues: Ensure that there are no connectivity problems or firewall issues that might be blocking the request.
Service Status: Ensure that the Memcached service is running and accessible. If Memcached is not running or is misconfigured, it can lead to errors when trying to enable it.
I would recommend you to discuss the problem with your hosting provider as they should be able to review the server logs and provide more information about it.
Best regards,
Daniela Ivanova
