What is happeaning is that I allow anonymous comments on our site. We have it set up so that all anonymous comments have to be approved first before displaying.
So they have to fill in the "name", Subject is filled in by default, and a comment. Then press add. At this point, the system should launch an e-mail to me telling me that I have comments to approve for display. After all three fields are filled in, they are getting the above error message and comment is not saved.
This was working until a couple of days ago, then just stopped and started generating this message. I have upgraded to DNN 4.8.4 and the latest blog release and am still getting the same problem.
