Restoring Administration Block in a Course

Add &bui_editid=10 to the end of the URL.

The ID for the Admin block seems to be 10 in Live, 70 in Dev.

 

If the block disappears site-wide, check the database for the correct "pagetypepattern" setting.  Anything other than "*" is incorrect.

MariaDB [mdl4]> select * from mdl_block_instances where blockname='settings';
