Greetings -
The majority, if not all, of our courses are set as "Topics format" in the Course format setting. Recently we started noticing issues when manually backing up courses. Namely, we cannot back some of them up. Instead, we get "error/setting_invalid_ui_label".
This doesn't happen on every course, just on some of them. I cannot figure out the pattern that throws the error for one course, but not the other. They have all been moved around into different categories; they all are given the "Topics" format upon creation; the naming convention is the same for all courses. The error is thrown on courses that are chock full of content, and courses that only have 1 URL in them, so course size doesn't appear to be a factor.
Once we change the format from Topic to Weekly, the course will backup just fine. When we change it back to Topic (which is what we prefer to use), we run into the error again.
The documentation on the error is pretty worthless, as there isn't any.
We have 2 sites, one running 3.0 and one running 3.1 - it's happening on both instances.
Any suggestions, aside from changing all 1800+ courses from Topic to Weekly format, would be most appreciated. If additional information is needed, I'd be happy to provide.
