Hi everyone, I've been working on Artisteer 3.1 skinning for the new release, and had this old "house" issue pop up for me again. Joe Audette gave me a permanent solution today that you may want to consider: It used to be that for new sites, the field mp_pages.MenuImage would get populated with 'house.gif'. This is not true for more recent builds of mojoPortal. So for a database solution to get rid of the house permanently for "legacy" sites like ours, you can do a database update like this:
update mp_pages set MenuImage = ''
Keep in mind that mojoPortal caches database reads, so it may take a little while for this update to take effect.
I hope some will find this useful,
Jamie
