so i have copyed the source code from a normal page, the footer and header part and included that in the file, instead of using <?php get_header(); ?>. so no off course its working, but that not a good solution at all. so you see, in single ticket, the header and footer <?php get_header(); ?><?php get_footer(); ?>, its getting its data from somewhere else. i can provide you with login data on ftp and backend if you want to have a look, because this is way over my head.
