Broken pages disabled in Apache due to SSI

Some pages are broken in the site and the HTML source displays comments like the one below: 

<!--#include virtual="/content/geometrixx/_jcr_content/par.nocache.html/geometrixx/components/text" -->

Environment

Dispatcher installed on Apache HTTP Server or other Apache derived web servers such as JBoss Web Server, IBM Web Server or Oracle Web Server.

Cause

The AEM application uses Server Side Includes (SSI) but SSI hasn't been enabled on the Apache HTTP Server.

The AEM application might be using Sling Dynamic Includes.

Resolution

To fix the issue, refer to the Apache HTTP Server documentation to enable Server Side Includes:
