Hi. I had Plex installed and running fine on OMV 0.3 (I beleive Plex was version 9.7.7)
Updated to 1.0.29 today, installed extra plugins, updated it to 1.0.13, enabled plex repo, installed it from SSH at first and then installed it from the Web GUI just to be sure. Plex shows up in the Web GUI, I then enabled it in the settings: I can't access it using a browser on the local network (tried the localip:32400/web, localip:8888/web and localip:32400/manage with http and https without success).
Logging in via putty on my OMV machine shows that PMS is indeed running. I have verified that port 32400 is still forwarded in my local router and it is (both tcp and udp).
Here is the result of my stat /media/6144c800-d52d-4468-bfae-96a8e4a823a2/plexmediaserver

And the result of my id plex
Permissions (111) seem right, I'm not sure what I should try next
