Blocks

Thanks for your reply atw...
It appears that Moodle has fixed itself... on logging out and logging in again (14 hours later), it now not only allows me access to the course (which it did not before), it has also reposted the administration and "blocks" blocks.
To answer your question... it was in a course, I was logged in as administrator, and I definitely did delete ALL the blocks from the course. The center panel was displaying wall-to-wall.
Lesson learned... don't delete the admin block! Hiding it will have the same effect in student view.

Thanks!
