Please update your question with the exact error message, and details about the vocabulary you created (including its name -- you may be using a reserved name).

Hi,

It looks like you're using a widget that requires a hierarchical vocabulary with a simple vocabulary with no "parent" column: if so, either the widget, either the referenced vocabulary should be changed.
