The upgrade from 2.2 to 2.3 run without an error or hitch.
All courses (tests & minor) with IDs 1-4 and 6 are fine. Our flagship course id5 (due to be launched in August) does not display - just heading & breadcrumb (see pdfs - screen print ... browser source added later).
It shows up everywhere it should (site admin, my course list) but can't get into course.
Decided to backup the course - all components showed in backup dialogue, and backup completed OK.
Restored course (from couse backup prior to upgrade) to new couse (id7) ... this also displays as just the heading & breadcrumb.
Has anyone seen this before? Can anyone suggest what is wrong and what has to be changed to make the course display?
