Our website is http://www.bostonknitting.com/ Twice in the last couple of months the main part of all the pages has just disappeared. All that was visible was the header area. No one had made any changes to the site.
Once I managed to fix it by applying a backup of the entire site. This most recent time (yesterday) I applied all the updates available to the Atahualpa theme 3.7.3. I was already at WorPress 3.3.1. Everything seems to work now, but I'd like to get to the bottom of why this happens.
