Was this issue ever resolved? I am also having users get "require login error" with a sub-header of "Course or activity not accessible." In my case, it is when they follow a link to self enrollment in a course. If they click the "X" box, they are able to self enroll in the course. But I am afraid the error message will cause students to simply give up and walk away. Thoughts?
