Just fired up the old VMware moodle, and email-based self registration worked fine. So I copied the files for moodle onto the new HyperV server as suggested, with no success.
Any other ideas? Got about 40-50 students who need to enrol at the start of next week and I don't wanna do it manually ^^
Hmmm ... so what are the new (if any) errors in apache logs?
Are there any other errors reported when in debugging?
Does the DB user have access rights to create temporary tables? Did you re-check permissions/ownership on all files/folders in the new virt environment.
To get students in right now, one might try bulk upload.

However, would warn that one might find other issues lurking.
