What do these errors mean and how do I track down what's wrong? I don't get any error messages while browsing the SharePoint site.

Hi,I searched for your error and found a link for the same. Search the text "SearchBoxEx AfterDeserialize begin" and read the blog posted by the author. Hope that helps.http://blogs.msdn.com/smungara/default.aspx

Hi and thanks for your reply. I read the blog but it don't have the problem of search results not showing up. I did try editing results.aspx and unchecking “Display Discovered Definition” but the error still occures. The webpart Search Core Results is present on the page. Refreshing the search page (results.aspx) logs a new error. The same error is logged when I refresh peopleresults.aspx.
