NamelessMC

I installed nameless but when trying to login or verify from the site this error is given:

There was an error loading this menu. The website owner needs to follow these steps to fix it:

1. Make sure the hostname value in core/config.php in FTP matches your site url.

2. If you are using the www. prefix make sure the force www option is enabled in StaffCP -> Configuration -> General Settings.

I tried everything, I put all possible hostnames:

sitename .it

www. sitename .it

https://www. sitename .it/

https:// sitename .it/

and I have already tried to force both the www and the https but nothing, how can I fix it? Maybe it's a CloudeFlare problem?
