REST API install problems

Tags: #<Tag:0x00007f433e118928>

I wanted to try out the REST API.
I installed the REST DOC through PaperUI/addons/Misc.

When I click on the REST API in the OpenHab dashboard, I end up with this screen… What did I do wrong?:

Sorry, forgot to add. Using Openhab 2.2 on a Rpi3.

any useful log entries from openhab.log ?

Not what I could find.

Try Clear the Cache

Made an upgrade to the system, including Openhab 2.3
Now I got a log (VERY LONG) when I try to enter REST Api:
