Just a quick update sorry. I found that it's only the third level menu in that has the issue.
For example, my pages that reside at [[linux:ubuntu|Example Page Here]] all work perfectly
However, any page under that [[linux:ubuntu:3rdlevelmenuhere|3rd level Example Page Here]] does not render.
But: If I take out the words Return To Main Menu in front of the syntax (which I placed there because I wanted an easy description for users) and just leave the syntax at the very left had side of the input box, it works perfectly
[[linux:ubuntu:3rdlevelmenuhere|3rd Level Example Page Here]] Renders properly no matter what
Return to Main Page [[linux:ubuntu:3rdlevelmenuhere|3rd Level Example Page Here]] Does not render properly.
