i have Codesys V3.5 SP19 runing on a raspberry pi.
At Codesys dialog settings from Visualisationmanager I select the dialogs from library VisuUserManagement (VisuUserManagement.VUM_UserManagement).
At the webvisu I can open the User management dialog and it shows the currently existing users.
My problem is that adding a new user at this dialog does not work.
To my procedure, I enter user name, select a user group and press Ok. The dialog closes but the user was not created.
Does anyone have an idea why add user does not work?

Best regards,
