Panels in SO Settings and Maintenance does not show any data

I installed the lastes SuperOffice Onprem version 10.5.4, and everything went well. When I logged into the SoAdmin 'Settings and Maintenance' the screen looked like this.

The menu is there, but no content in the panels on the rigth. When I go into the 'Developer tools' in Chrome, an error shows up, - here it is

It seem like the problem is with the SCIL javescript. Does anyone know how to fix this problem.

We tried removing the whole installation, and doing a reinstall, both on the new database and the existing one.

Does anyone know, what this problem can be solved ?
