downgrade lost ui

[nilew]

Hi,
since it seems that v.2.2.0 has some errors I decided to do a downgrade to 2.1.1.
I tried it via commandline and via the gui.
It says it has the right version but I lost the webgui.
The page is just blank, I tried via the https://find.z-wave.me/zboxweb and directly to the ip.

What could be wrong? did I downgrade wrong?

thanks

It seems the was a problem with my webcache.
Works now.
