Hi,
I copy the information about an error as informed at the log. It was triggered during the normal working of a live public DW site. It looks related to an authentication process, but not special permissions are needed to visit the url that triggered the error.
Does anybody have a clue about the reason and how to fix it?
Regards,
Tomas
