Post by ron-rp on Errors with VisuUserManagement library

Hi all, I've played a bit with the VisuUserManagement library, and some other security option in my project, and I started getting this error when logging in - see attached pic. something to do with a specific screen in the library - VUM_Login. Also, Codesys started to ask me to log in to the library when logging in, asking to log in as user of the groups Maintainer or Owner, which I dont know either users (attached pic). when I close the login screen and try to log in to the PLC again, everything works again until I close and open Codesys. I do use user and password to login to the PLC, and this login screen is fine I know the user and pass I setup. anyone know what did I do wrong here and how to fix it?

To search for an exact phrase, put it in quotes. Example: "getting started docs"
To exclude a word or phrase, put a dash in front of it. Example: docs -help
To search on specific fields, use these field names instead of a general text search. You can group with AND or OR.
