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?
