We are using Authorize.net Gateway as the payment merchant with Moodle 1.9. This is a recent upgrade from 1.8. With 1.8 a student would pay via Authorize.net Gateway and then be directed into course room. They were then able to access course.
In 1.9 the payment is accepted, but the student is logged out when they log back in they are unable to access the course they just paid for.
The students name is listed as a participant in the course.
When an admin clicks on the students name in the course room the screen stated that the student "is not enrolled in this course"
The course is not listed in the course list in the students profile.
