When clicking any button on the OnBase tab, a general exception occurs:
System.Configuration.ConfigurationErrorsException: Configuration system failed to initialize ---> System.Configuration.ConfigurationErrorsException: Unrecognized configuration section
This may occur after upgrading from a previous version of the Office Business Application for 2021. The issue is that the user configuration settings that were preserved from the previous version of the software cannot be accessed by the upgraded version of the software.
To upgrade and preserve the user settings, see Upgrading While Preserving User Settings.
To upgrade the user settings file without preserving the user settings, see Upgrading Without Preserving User Settings.
