Free SSL installed but not working. ???

[natali_]

Using Linux & Wordpress

I've installed free SSL from Let's Encrypt to cPanel. It's installed & done

I've added the following code to .htaccess:

RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

I've changed the URL to https:// in Wordpress & added the code which can be found here to the .htaccess file:

https://www.godaddy.com/help/redirect-my-wordpress-website-to-https-for-linux-hosting-27871

I've changed the "coolexample" part of the code to my domain

Still, when i visit site it's "not secure". 

WHAT CAN I DO FOR IT TO WORK?

Greatly appreciating help.

What is your domain - and have you done "inspect element / page" to see if there are any images loading over HTTP??
