I’m probably too late, but maybe someone else has exactly the same question

how did you find the right destination path?
Under Websites & Domains (domain.de) select the PHP settings and click on “View the phpinfo() page” behind the activated “PHP support (PHP version xyz, run PHP as xyz)” box.
There you will find the path under “_SERVER[“DOCUMENT_ROOT”]”
Should then look something like this: /var/www/vhosts/hosting.netcup.net/httpdocs/domain. Then all you really need to do is look where your .htaccess is.
Recently I also had to deal with the error 500, which was ultimately due to a misconfigured .htaccess The start page was displayed correctly (except for the fonts), but all other pages then showed an ugly 500 error.
