Error with Advanced Adaptive Release.
When trying to delete a rule created with Advanced Adaptive Release, the following error is encountered:
Access Denied Either you are not logged in or you do not have the appropriate privileges to perform this action. You may have access to other parts of the course.

As a work-around, go into the rule and delete all the criteria, no access restrictions will be in place to prevent access, even though the rule is still present.

Try deleting the Rule(s) in Safari – Joseph and I tested this today and it worked!
