Just a note to share a problem I ran into inadvertently... and also solved. I installed Moodle on my website that is set up for FPage. I don't want to use FPage, but it was set up that way initially. When I installed Moodle, then tried to run it, I kept getting errors saying things about "_vit_junk" folders--- folders that were created within every folder of moodle!!!!! Any time the scripts in Moodle tried to access such folders-- horrible error messages popped up like so many lawn-weeds.
I manually weeded.... (deleted all the FPage created folders).... problem solved.
