Sounds like a character encoding problem to me. Allthough I tried changing my Page.ss to UTF-8 with BOM but nothing hapened.
Well, the only time I encounterd something like that is when I saved my files as UTF-8 with BOM (certain specialized text editors let you do that, like BBedit on mac) and then certain php code that needs to be at the top of the page can not reside at the top of the page anymore because there is a tiny snippet that says waht kind of character encoding you are using. The right way to save a page is UTF-8 NO BOM (when you are aiming for UTF-8 + your server can deliver that and modern servers can).
but I don't modified that page. It's original SS page. I use Notepad++ Text Editor or Netbeans...
