I have just taken over a wordpress site. On most of the pages the letters "de" appear at the very top - totally unrelated to the content of the page. When I look at the source of these different pages I see that these pages start with "de" and then the actual markup begins.
For example:
de<br/>
or
de<!DOCTYPE html>
Any ideas where to look for where this code is coming from? Looking at the URLs I have tried admin.php and index.php but beyond that I'm stumped.
