I have successfully added Let's Encrypt SSL certificate for my Sever Hostname/FQDN but the issue is that When I am logging on my Roundcube mail , The messages is not showing on a same Frame. Open the file # vi /usr/local/apache/conf.d/ssl.conf Header always set X-Frame-Options DENY and can be changed to # vi /usr/local/apache/conf.d/ssl.conf Header always set X-Frame-Options SAMEASORIGIN Now login to your webmail and check .
