Apache Directives not working after Apache update

After manually updating Apache on Debian 11, the Apache Directives in the ISPConfig site settings do not work.


RemoteIPHeader CF-Connecting-IP returns the IP of the visitor, not the IP of the Cloudflare CDN.


After updating the Apache manually, it does not work.
Updated Apache version is 2.4.57.

When you add Apache Directives in ISPConfig, no content is added to /etc/apache2/etc/apache2/sites-available/domain.vhost. What's the problem?

 

The required mod is not enabled.

Code:

sudo a2enmod mod_remoteip

 

I solved the problem. Can I delete the domain.vhost.error file?

 

Sure but if your settings are already correct it will be changed to a proper vhost file and there is no need to manually delete it.
