Hi! Thanks for your answer.
When I accessed the correct server I found the TimeZone settings. :-)
However changing 'UTC' to 'UTC+1' was wrong, how should it be written?
$conf['timezone'] = 'UTC+1';
PHP Notice: date_default_timezone_set(): Timezone ID 'UTC+1' is invalid in /usr/local/ispconfig/server/lib/app.inc.php on line 32
