Checkmk Werk 14292: Fix possible broken web access after updating to 2.1.0p10

ID: 14292 Title: Fix possible broken web access after updating to 2.1.0p10 Component: Site Management Level: 1 Class: Bug fix Version: 2.2.0i1 Checkmk 2.1.0p10 changed the handling of the apache configuration with werk #14290. This change introduced a new issue which could break the system apache configuration in case a sites apache configuration was not yet updated to the new system apache configuration. The problem appears because as of 2.1.0p10 the file <tt>etc/apache/apache-own.conf</tt> was removed from all sites. However, this file must only be removed for sites which already updated the apache config. In case you experience this issue, you can either update your apache configuration with <tt>omd update-apache-config [SITE_ID]</tt> or restore your old <tt>etc/apache/apache-own.conf</tt> in your site and restart the system apache again.
