No Bindings listed at Inbox

I came from openhab 1.8.x. Today I removed openhab 1.8.x completely and installed openhab2 via apt package as written in
I can start openhab, open PaperUI, config system and also i can install add-ons. I get no warning or error. Everything seems fine. But If I look at Inbox and press the plus button, the list of bindings keeps empty. Also at configuration/bindings I see no entry.
I installed ComfoAir Binding, MQTT Binding and Novelan Heatpump Binding. All of them are marked as installted at add-ons/bindings.

I use an Odroid XU4 with Ubuntu 16.04.2 LTS.

Please help me.

OMG… I should have read

But still not working. when starting openhab2 log shows:

Why is karaf deinstalling my bindings?

Maybe because of this?

Thanks very much. I filled the line binding in addons.cfg … but because I use 1.x bindings, I have to add a 1 to my binding names. For Example:

binding = mqqt1,novelanheatpump1,comfoair1

I use some 1.x bindings (weather, fritzboxtr064, mail) but i have not touched addons.cfg and they all work.
I just installed them via paperUI and edited the corresponding cfg file for the binding where needed.

Hi guys, from yesterday my Bindings list and Inbox are totally empty!
all the rules…items…and sitemap seems to work properly but I can’t add or modify any binding.
It didn’t happen after any update or refresh. I was working on the rules and items files without touching bindings configuration.

Do you know what should I do?

Please help
