Question

Why is Force HTTPS Redirects disabled in the Domains icon of cPanel?

Answer

There are a few possible causes for this issue:

• The domain does not have an SSL certificate.
• The Allow cPanel users to install SSL Hosts if they have a dedicated IP option in WHM's Tweak Settings is disabled.
• The mod_rewrite module is not installed.
• Apache template overrides have been installed, which are modifying the part of the configuration that allows for the use of this feature.
• The permissions on the /usr/bin/rpm and/or /bin/rpm binary are incorrect. Permissions should be 0755.
