Hi,
I’ve done this : https://board.jdownloader.org/showthread.php?p=415478
And since then i cannot connect to my dashboard or rutorrent with my browser.
I’ve tried to disable jdownloader.service and to remove Quickbox directory and reinstall it.
Can anybody help me with what i’ve done please ? 
I can PM my IP.
I’m on Ubuntu 16.04 I’ve got the last version of Quickbox.
EDIT:
Looks like Apache2 is dead :
systemctl status apache2.service
