Hello,
When I am editing a course, I am unable to delete activities, bell works, or anything for that matter. When I attempt to do so, I simply get an error message that says "unknown error." I have tried to use google chrome and safari, but the error message remains the same. When I attempt to delete the content, the error message appears, the content disappears briefly, but then the content will return when the page is refreshed.
Any suggestions?
