Object reference not set to an instance of an object

  1. 4 months ago

    Since our upgrade on the Feb 13th, we are not able to save certain elements of our configuration. In the error logs, this is what we are seeing. I am hoping we may have found an undocumented feature or perhaps there is a reason for this and an easy fix we can make? Any assistance would be great! Thanks! Jimmy

    What specifically do you do to recreate the error?
