Hello, this isn't really an AutoView issue, it's a generic Moodle problem and the answer will somewhat depend on the set up of your web server and PHP installation.
Have a look here:

for more information. If you still have a problem I suggest you post on the forums at Moodle.org, where you will get a much better and quicker reply.
