    Hello,
    How can I reproduce this error?
    Could you send the error details from ScadaWebBeta\log\ScadaWeb.log ?

    The error comes only when I try to change the config of webbeta in web configurator, I changed the break between diagram points from 90 to 20 then, after saving and restarting server, this error occurred on login page, for old web app no such issue is observed that is working fine as desired.

    Thank you. I think, I’ve found the cause. But it is strange that this error occurs. Does it occur every time when you try to open a view or only once?

    Do not use Configurator for the new web app, it breaks the config. Override the ScadaWebBeta\config folder from the distributive. Edit config manually using any text editor.
