Hi all,

Trying to add a quiz on Moodle which works ok when adding a new question, but when I go to add a second question I get a 500 error.
This doesn't happen if I go to Update Quiz after every question I add which is a bit of a pain to do for every question.

When the 500 error appears, I noticed that the URL is odd looking (not knowing what it should look like though).

Code:
http://moodle.website.com/question/question.php?category=421&cmid=8134&returnurl=http%3A%2F%2Fmoodle.website.com%2Fmod%2Fquiz%2Fedit.php%3Fqpage%3D0%26amp%3Bcat%3D421%252C12913%26amp%3Bcmid%3D8134&qtype=essay
The bit that sticks out the most to me is "http%3A%2F%2F"?
