Hi Giuliano-
If you’re seeing a 403 error, I’m thinking you’re running into some kind of security or firewall issue.
Try disabling any security plugins you might be using and see if the error persists.
If you’re still seeing it, it may be a server-level security setting. One good first step would be to check your Apache or NGINX logs and see if you can find any errors logged there. Your web hosting provider or System Administrator may be able to help you locate these logs and check for the error.
