Expected results:
The help page is present and displayed without any issues.

Additional info:
There is the same problem with the 5.7 version of Satellite 5.8 proxy documentation, as the Satellite 5.8 contains all version of this document back to the version 5.2. Most current version of the Proxy Installation guide (5.8) doesn't suffer from this issue.
