Any support?

That error occurs when you move, rename, or delete a question that was referenced somewhere else, such as in case management.
There should be more information included with that error message - I think it also details the bad reference. To resolve, you need to find the place where that question is referenced and either delete it or update it to point somewhere else.

How to find the question was referenced somewhere else, such as in case management. Any Automated to find the referred question?
