Just a small thing that probably isn't the problem, but take off the trailing / from dirroot.

$CFG->dirroot = "/home/loveq8/public_html/moodle";

The path looks OK, but have you made sure that ALL the files were copied or installed correctly?

For example, are you SURE that there is a file setup.php in the moodle/lib directory?

Completely bizarre. I had a quick look at the site and the quiz maths is quite wrong.

I can only suspect some corruption somewhere. It could possibly be related to a couple of quiz bugs that were fixed recently.

In any case, the solution in this case is to re-create the quizzes and to always use the "save grades" button on the quiz while creating it (even if the grades look OK already).

The bug related to the "save grades" button is not in current CVS versions of Moodle, or the next release.

You're going to have to provide more information if you still need help with this. The grades shouldn't be turning to zero, obviously - I've not seen that before and can't guess what might be going wrong.

One thing I'd add is that I believe these days HP hardware usually often ships with Linux, so it's win-win, probably.

I appreciate the offer - I'll email you privately about a "consulting visit" as it's not appropriate for this forum.
