SSL and template joomla

I want to ask for help or advice. I already have experience installing the SSL for the Cloudflare. Previously, to restore the template, I installed the plugin Cloudflare For Joomla, then in the file configuration.php I wrote the line $_SERVER[‘HTTPS’] = ‘on’; and the template was added. with this site does not work. Help me please.

It looks like you are experiencing issues with Mixed Content on your site, which is preventing the SSL lock. Have you tried this?
