I just upgraded (via omv-release-upgrade) from 2.x to 3.x. I'm having some issues the main one is that when I select to activate Plex(see screenshot) or any other activity that you need to "switch on" I get the following error. I have tried to make sure a apt-get update was done and all files updated.
So when I click on ENABLE and click SAVE I get that popup error.
I'm running 3.0.76
Thanks
