Hi
Just doing the basic configuration and can't save without getting the 403 error
What to do?

Hi,

This usually indicates that your server has some security system which blocks the request.
It's probably because the configuration has too many settings for the maximum number of parameters allowed.
The best would be to check with your hosting about that issue.
