Switching from http to https

I have having difficulty in switch from http to https on my Web sites. Here's the issue. For your information, I have access to WHM and to cPael for all my domains. I created I ran Auto SSL within WHM for a particular domain, and now the domain loads in a Web browser as both http and https, but I only want it to point to https. I then went in and created an .htaccess file with this code to create a 301 redirect. RewriteEngine On RewriteCond %{SERVER_PORT} 80 RewriteRule ^(.*)$
