This is a lot like the problem I’m having. For some reason, suddenly I’m getting weird strikethroughs in my side bar and in the last post on the main page. I can’t figure out why this is happening. I’ve deleted comments/posts that might be suspicious, but nothing’s helped. I even upgraded to the newest version of WP and changed the theme–still no luck. How can I figure out where the problem is if it is a bad post? What other things might be causing the problem? Thanks!
