MediaWiki 1.19.0 PHP	5.2.6 (cgi-fcgi) MySQL	5.0.67-log

Because of a server error my wiki-directory got deleted, luckily my database was still intact so I took the opportunity to install the newest version of MediaWiki. While doing this I got a strange bug on my page. It looks like all pages have redundant code in the header:

<!DOCTYPE HTML>  Untitled Document

Just before the page itself. This results in all pages having "Untitled Document" as the title. Is there a step I've missed in the installation of the new version?

Thanks for any help.
