Hello SPI,
we will try to reproduce this, to be able to do so, please tell us a few more infos:

  • The OS version of the server
  • Did you perform update from older version of avast! Administration Console or fresh new installation?
  • The browser you are using
  • The details about error provided by the browser (it seems that Firefox and Chrome are much more verbose than IE in this area)
  • The URL you are using to access the console

Thx. Jan.
