Plugins not installable/compatible??

Hi,

I am trying to switch my OMV setup from an OdroidC2 to a Hp Microserver (Athlon x2), and though I got it up and running fine I can't seem to install any of the plugins I use. They aren't even visible from the OMV web interface. I've tried to install a miniDLNA manually but can't see it on the GUI... and am getting confused. DLNA, VPN, TRANSMISSION, all were immediately installable through the GUI on the previous setup.

Thanks!!

Ah I feel stupid.
Thought I had already done that...buuut I hadn't.

Thank you very much.
