Yes, please open your Global.asax and find the following code:
Public Function GetUserDisplayName(ByVal useruniquename As String) As String Implements CuteSoft.Chat.IHttpApplicationDataProvider.GetUserDisplayName
Return GetUser(useruniquename).FirstName
End Function
Please change it to
Public Function GetUserDisplayName(ByVal useruniquename As String) As String Implements CuteSoft.Chat.IHttpApplicationDataProvider.GetUserDisplayName
Return GetUser(useruniquename).Username
End Function
That will resolve this issue.
