Somehow I seem to have deactivated the type of relationship 'Household member' (is a member of what household) through the interface while configuring a fairly new CiviCRM. As a result, I don't seem to be able to associate individuals to households. Nothing has been changed in code, so I must have just clicked on something. On the relationship types page, this relationship (is a member of) is of course still there (it can't be deleted through the interface, afterall), but doesn't allow itself to be actived (though other options like 'child of' or 'spouse of' can be activated and deactivated). I'm the only person who's been configuring the site, so I don't see how it can be a permissions issue (it must be a problem that I created).
Any ideas what I need to do to re-activate this basic relationship type?
Thanks very much!
