Seems I made a boo boo in Moodle. Tried restoring a course, and selected the "delete existing course and create in place. Anyhow, long story short is that the front page is now an empty course with no blocks (but room to add blocks, activities, etc etc. The rest of the site is in tact by the looks of it (can manually browse to courses).
What's the best way to restore the front page?
