.htaccess -> Primary script unknown

Hello,

Today I installed a server following https://www.howtoforge.com/tutorial...-9-stretch-apache-bind-dovecot-ispconfig-3-1/
When testing a website (php-fpm) with this .htaccess:

Code:

RewriteEngine on
RewriteRule ^index.php / [R=301,L]
RewriteRule  ^[a-z0-9]+\.[a-z0-9]+$ - [NC,L]
RewriteCond %{ENV:REDIRECT_STATUS} ^$
RewriteCond %{REQUEST_URI} !^/stats/.*
RewriteCond %{REQUEST_URI} !^/scripts.js.php
RewriteCond %{REQUEST_URI} !^/style.css.php
RewriteRule ^([a-z_0-9/\.-]+)$ myfile.php/$1 [NC,QSA,L]

I get

when visiting my.site/mydir
On the previous server it redirects 'mydir' as parameter to myfile.

Suggestions/ideas to solve this?

 

I have a related issue:

what strange, there is still no reaction after 2 months
Where can I go to get support if there is no support for this on this forum?
