I  setup  apache mpm_event  with php7.4-fpm and all seems to work fine. I used this help: https://www.digitalocean.com/community/tutorials/how-to-configure-apache-http-with-mpm-event-and-php-fpm-on-ubuntu-18-04 But after i setup and configured Froxlor and start it with the command in the cronjob /usr/bin/php -q /var/www/froxlor/scripts/froxlor_master_cronjob.php --tasks 1 many problems started and the hole Froxlor website was not more accessible. I forgot some checkboxes
