I think you are likely to find the issue lies with XAAMP rather than Moodle. The server/php/dbase setup has something funny in it, I'm sure. Never been keen enough to track it down, even if I could, just gave up on it in the end. There just seemed a cascade of failures that was just frustrating and all, I suspect, stemmed from the same cause. Seriously suggest you dump XAAMP and rebuild as a complete server solution of your own.
