In the process of attempting to copy a course, I initiate a backup. The course has hardly anything it it, yet the message " There is a pending asynchronous backup for this course. Please do not edit this course until backup is complete" is just ongoing. Been that way for many hours. How do I kill a pending backup? I'm a real novice at this stuff, not familiar with server commands, etc.. I tried deleted the course, but can't delete it because the backup is pending. Upgraded from 3.9.1 to 3.9.2 hoping that things would reset. No help. Cleared cache, no help.
