I have TWO "Course Administration" Blocks in the same course!
How can I get from one of them!!
Ok- that may mean it's locked - Go to the admin block and click on site administration - plugins - blocks - manage blocks
there will be a lock icon next to each block installed on your site. Ensure the lock is toggled to "unlocked" next to the administration block - then you will be able to delete it and you can relock it after that.
Recently inherited some admin privileges. Similar challenge: two Accessibility blocks in a course: one set up at the System level to be visible on every page; the other at a course level.
As admin, how do I delete the course-level default?
