To be clear on a response for possible future users running into this, it is not a native Sentora issue.
I added it on the direction of a good post on how to get an excellent security rating for you Let'sEncrypt cert. If you secure your panel alone as per that tutorial/guide, that will not cause issues, but if you follow the "hardening" instructions for your certificate as published here in the forums there are two places you will be copying and pasting the problem entries:
One in the file /etc/httpd/conf.d/ssl.conf
Header always set X-Frame-Options DENY
Which needs commented out.
And one in the Sentora panel @ Admin > Module Admin > Apache Config > Global Sentora Entry
#Header always set X-Frame-Options DENY
If you do this from the get-go as I will now, you ill have no issues, but if you run into the failing Sentastico display issue, this is a simple edit and can be found in the Global Sentora entry in the panel.
Thanks for the the assistance TGates!
