Web Gui throws errormessage: webgui unusable

  • After updating omv from 3.xx to 4, the webgui throws an error message, ONLY when I log in as admin.
    Probably the webgui tries to show the amount of memory, but in the wrong or omv3 way? I received no error message during the upgrade from 3 to 4.
    Other services seem to work without exception.


    Please help.


    Below the error message.

  • I found a temporarily solution:


    Click the close mark x as often as needed to close the error message.
    Then quickly close the system information part of the dashboard.


    I have no system information screen anymore, and also no error message.


    When I try to activate system information, the error message returns.
