Did you remember to add:
to the end of the Global Sentora Entry? (Admin > Module Admin > Apache Config)
(Change panel.domain.com to your panel login FQDN)
This should also remove the need of using the .htaccess additions.
Code:
</virtualhost>
# PORT FORWARD FROM 80 TO: 443
<virtualhost *:80>
ServerName panel.domain.com
ServerAdmin webmaster@domain.com
Redirect permanent / https://panel.domain.com/
to the end of the Global Sentora Entry? (Admin > Module Admin > Apache Config)
(Change panel.domain.com to your panel login FQDN)
This should also remove the need of using the .htaccess additions.
