After installation of this module, go to the Settings menu -\> Technical
-\> Database cleanup. This menu is only available to members of the
*Access Rights* group. Go through the modules, models, columns and
tables entries under this menu (in that order) and find out if there is
orphaned data in your database. You can either delete entries by line,
or sweep all entries in one big step (if you are *really* confident).
