I've nearly finished developing a site (www.meccs.org/site), and my customer has just started adding content, and suddenly when I go into edit-page in wp-admin, the attributes section (in which I specify parent-page, among other things) is blank.
Any idea how I can make this problem go away? I haven't recently installed any new plug-ins, and I can't imagine my customer has done anything besides changed the content of a number of existing pages I'd already set up for her - I'm certain she hasn't gone deep into the hosting server and changed the php code that controls this.
Has anyone had this happen to them, and figured out what causes it? Anyone have any ideas on how to make it go away, and NOT happen in the future?
