Yep, PATH_INFO stuff works waaaay differently in Apache 2.0.

For instance, this site required the PhpWiki:PrettyWiki .htaccess to read:

<Files space>
    AcceptPathInfo on
    SetOutputFilter PHP
    SetInputFilter PHP

Instead of the old tried-and-true

<Files wiki>
    ForceType application/x-httpd-php

Also, as a sidenote, the RedHat 8.x defaults for PHP break almost every single template in this Wiki. Mind you, the RedHat guys have their stuff correctly set up - it's just that the syntax here has been deprecated.
