All of my plugins have disappeared!
I am running Hoobs 4.0.98 (I upgraded to 4 from 3). It has been working perfectly until a couple fo days ago when my plugins disappeared (the plugins page says No plugins installed. Install Plugin). However my plugins are still working as can be seen from the log

and the accessories are visible in the home app and work as expected.

Any ideas?
