<?php include "CMS/Connections/localhost.php"; ?>
<?php include "CMS/WA_CMS/WA_CMS.php"; ?>
... ah hah! relative paths strike. :( My path was correct but PHP was getting to the wrong place somehow.
What I have:
so I told it "/cms/(files)" and it was not going to the site root folder. Switched off to "../cms/(files)" and now it's working. :D Thanks!
I wonder where / was making PHP look... I hope not in the actual system root! O_O
