Blank screen on all my add-ons after Update to Jarvis on RPi2

Just updated my RPi2 to OSMC 2016-02-1 & Kodi 16.0 and now getting a blank screen on all my add-ons. Advise please?

To get a better understanding of the problem you are experiencing we need more information from you. Please see http://osmc.tv/wiki/general/how-to-submit-a-useful-support-request/ for advice on how to help us.

It’s possible a problematic add-on isn’t ready for Jarvis yet. We just need to work out which one.
