Each and every page I try here suddenly displays a line with the word »or« at the top! This is in the page source:
Or <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
A typo when changing a site header file?
Or some hijacking going on?
