Any suggestions on how I can determine which page element the errors are coming from? Sidebar vs. other sections etc. I’m assuming the ul and li are from the sidebar but I don’t see anything wrong in the code and it hasn’t been edited at all.
They are all widget based and I ran the markup validation several months ago and the code on the sidebar hasn’t been changed since then.
To show where the errors are when you validate your code, select the Show Source option and then click the Revalidate button. Since one code error can cause a cascade of additional errors, it’s best to fix the most obvious errors first (like unclosed img, div, p tags), and this can result in some of the more bizarre errors going away.
