I have a problem when trying to backup my courses in MOODLE 2.2 At the end of every semester I need to do a backup of all the courses in MOODLE. When I try to do the backup I get a 500 Server Error and it will not backup. I did some troubleshooting and found that if the course does not have any quizes in it then it will backup with no problem. If the couse has an quiz in it then that is when I get the error. I am running MOODLE on a VM with Windows Server 200R2 with IIS 7 and SQL Server 2008R2. Any assistance would be most appreciated.
Thanks
