OK, this is my Installation:
Installing the Server with Ubuntu 16.04 and all Updates. I take a look in the Installation manual from wiki.razuna.com an d do a step by step installation from the system.
All points in the installation instructions up to ffmpeg made no problems.
Ffmpeg had an error in the compiling com source code.
After the installation I called the site and finished the setup.
In razuna admin I created a new host and announced me there.
Which I in the administration on custom fields to create a new one comes only once briefly the progress bar, that's it.
The fields appear nowhere.
Chrome version 56.0.2924.87 (64-bit)
But also in the edge and firefox is no change.
Even in the docker container with the version 1.8 contained in it, the same problem exists.
