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 </Files>
Instead of the old tried-and-true
<Files wiki> ForceType application/x-httpd-php </Files>
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.
