Hi, I'm running the most current stable version of pi-hole on an rpi. I want to use an iFrame on an intranet page to display the pi-hole web interface. To achieve this, I have changed below parameter to ALLOW: "X-Frame-Options" => "ALLOW", Of course, updating pi-hole will revert this setting …

Try this: $HTTP["url"] =~ "^/admin/" { setenv.set-response-header = ( "X-Frame-Options" => "ALLOW" ) }
