I have a client site, [url removed, login to view], that has a blog as part of it at [url removed, login to view] Problem is that I hit the button to upgrade to WordPress 3.1 in the dashboard, and now there are error messages when you go to that page. I did back up the database before upgrading (attached). But I don't know how to fix the problem. It is a very small blog with just a few pages and posts; nothing complex. It has only been around since October.
