This page describes what to do when the following error message is displayed.

Note that even if two or more categories cannot be deleted, this error message will only include one category name.

The category you are trying to delete cannot be deleted since there are records classified under it.
This error message appears regardless of whether the Category feature is enabled or disabled.
