I'm experiencing a problem with the login widget using SF8.1.5810.0 + Feather 1.3.340.0.
When I place it onto a page I get an error, "Exception occured while executing the controller. Check error logs for details." However nothing ever gets written to the error logs so I'm sort of dead in the water as to what maybe happening. This happens in design mode and while viewing the public facing page.
Any ideas on where I could look to figure out what error is actually being thrown?
