Thank you very much! I managed to correct it, by checking the code on my other website, it was the text error, i guessed i had deleted to much text, which i had, because i just cut and pasted the part below, which i suspected was to blame. The words missing was "This is the main define statement for the page for" english

define('TEXT_MAIN','This is the main define statement for the page for english when no template defined file exists. It is located in: <strong>/includes/languages/english/index.php</strong>');

Up and running again, thanks!
