I had the plug in working for at least the templates but hadn't set anything else up. Last night, I installed the latest update and now nothing is working as expected. Site titles aren't being 'read' for snippets, sometimes they're being read and regurgitated over and over. Excerpts aren't being created. It's a mess. I just tried creating my xml site map (this is a brand new site) for the first time and received the error below. I doubt anyone can help since the problems I'm having are so erratic and systemic and I'll probably just have to trash this plug in. I really want it to work but the way it is now, my snippets are just either ridiculous or nonexistent.
