Hi champs,

we are in a situation where Dynamics 365 Portal has started behaving weird. All of a sudden it giving this error when clicking on "Register" on Sign In page.

Initially it was giving us custom error but then we turned off the custom error and got following exception.

Any hint, suggestion and help will be appreciated.
