When I go to some manual pages on one of the Norwegian PHP mirror sites (no.php.net), I get weird HTML output, like for example:

http://no.php.net/readline returns:

And other pages return similar results.
Other pages, like http://no.php.net/date, or the full URLs of the pages above (like http://no.php.net/manual/en/function.readline.php), works fine.
