      Hi Davo. An odd bug to report here, as UploadPDF seems to be the culprit but has been working without problems for a long time.

      A user (student role) could not access a course, and was instead receiving an 'invalid course module ID' error. Teachers and site admins could access the course without errors. Upon locating the stack trace (below) it seems that the 'upcoming events' block was calling the UploadPDF class and failing.

      As a test I accessed the course as site admin and deleted the 'upcoming events' block, at which point the user who previously could not access the course, could. Upon adding the block back in to the course, the user again received the error.

      Stack trace:

      line 211 of /course/view.php: call to bootstrap_renderer->header()

      The course has just two UploadPDF assignments, one of which has a due date.

      Thought I'd better report it as I can't immediately think how to progress, but can supply any other information you may need.
