Last week, our various service desks stopped working. Each now gives the "...form contains a hidden field...." message. This occurs whether the initiator is a site admin or a regular user.
All fields on a screen are not hidden. Mandatory fields are configured correctly.
The only thing that I can find is that several users were removed from the environment (they were flagged as site admins). The fact that all of the service desks are now reporting this problem leads me to conclude this is a global setting/issue. I am not sure how to proceed. Any assistance/suggestions would be greatly appreciated.
