transmission unavailable since owncloud8

hello,

Since i installed OMV 8, the transmission plugins didn't work.

I imagine there are conflict between "apache" and nginx but i don't have enough knoweldge to solve it.

I did some search but i 'm not able to analyze them...

I have mysql + owncloud + OMV on the same server and only transmission is unavailable.
I didn't change default installation (port 9091).

root@omv:~# ps -ef | grep nginx
root 3824 1 0 juin13 ? 00:00:00 nginx: master process /usr/sbin/nginx
www-data 3825 3824 0 juin13 ? 01:08:33 nginx: worker process

dpkg -l | grep apache

all The ownCloud configuration for the apache web

root@omv:~# service apache2 stop
No apache MPM package installed

i did it now but same issue.

During installation of the pluggin I had
================= Error =================
Failed to load configuration (Fatal error 4: Document is empty (line=1, column=1); Fatal error 4: Start tag expected, '<' not found (line=1, column=1))=========================================
Processing triggers for openmediavault ...

but the installation continue and at the end I can see it on my plugin tab.

I have the same problem, when i open the webpage, unknown adress... the nginx doesn't load the page

same problem.

when i go on transmission pluggin in omv website, and i select torrents, i cannot add torrent or other action.
Nothing could be selected.

in the log i found
Jun 28 16:38:52 omv transmission-daemon: transmission-daemon Failed to daemonize: Permission denied (daemon.c:514)
Jun 28 16:43:37 omv transmission-daemon: transmission-daemon Failed to daemonize: Permission denied (daemon.c:514)

Jun 28 17:05:28 omv transmission-daemon: transmission-daemon Failed to daemonize: Permission denied (daemon.c:514)

after a reboot it's ok

thanks
