when delivering PHP files (contact forms), only “File not found” is currently displayed.
The whole thing happens on Ubuntu 18.04 with Apache, NGINX, PHP-FPM and Hestia v1.5.11.
The files are of course there. Is the problem with Apache or Nginx?
Could there be a problem in /etc/apache2/php(version)-fpm.conf?
There are several lines in the error log
"[proxy_fcgi:error] [pid 32318:tid 139708709467904] [client xx.xx.xx.xx] AH01071: Got error ‘Primary script unknown’
