Impossible to redirect https to http

Hi guys,

I'm trying by all means, redirect all url that google has indexed me by https.
I do not understand how this could have happened, not if it was the fault of plesk.

This is what I tried:

htaccess

RewriteEngine On
RewriteBase /
RewriteCond %{HTTPS} on
RewriteRule (.*) http://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

Also I have tried through the directives of plesk for apache as seen in this screenshot:

Also I have modified the httpd.conf adding new rules, but neither.

Please know any solution to fix this.

Thanks

What kind of webserver is it?
Where is it hosted?
