                                  • Hi!

                                    From time to time an error happens in my client's XAF site.

                                    I attached log file and my solution.

                                    Thank you for any help!

                                Hi Vyacheslav,

                                Your logs show that the Request.Path property value contains the ":" character, which is considered as a possible attack evidence. Please try a solution suggested in ticket B155972 (An HttpRequestValidation exception occurs when entering a date value into the CriteriaPropertyEditor (.NET 4.0)). If this does not help, please provide us with detailed instructions on how to reproduce this issue.
