I've had the Auto Action plugin installed on a site for some time, but haven't used it. Now I would like to use it to join a member to a group when their access level changes.

When I try to add a new action I get an error:

1054 Unknown column 'parent' in 'field list' SQL=SELECT `id` AS value, `name` AS text, `parent` FROM `jos_kunena_categories` WHERE `published` = 1 ORDER BY `parent` ASC

From their I can't proceed. Any ideas on how I can fix this would be appreciated.
