Unknown column event_author

I don’t seem to be able to create an event at all. My site is public but I have a “hidden” page chriskernmusic.com/submit-new-event/ that by use of the guest login redirect, forces login in order to add an event. I get the [Unknown column ‘event_author’ in ‘field list’] and looking at the database the eme_events table indeed does not have this field. Have I missed a configuration somewhere?
