 * I don’t know why, but now whenever I edit a post, the following is displayed 
   as part of the post – The only way to stop it displaying is to physically edit
   it and remove it from the post.
 * `< ?xml version="1.0" encoding="utf-8"?> < !DOCTYPE html PUBLIC "-//W3C//DTD 
   XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.
   dtd">`
 * I have the following “ticked”:
 * `WordPress should correct invalidly nested XHTML automatically `
 * Would this have anything to do with the problem?
 * Could some WP guru explain why this is happening?
