When I go to the page the scan was requesting manually I receive a 500 internal server error instead of a 404 error message. Is there any way to either turn off the email alert of these type of errors or could their be an actual bug that needs to be resolved? I would really appreciate any assistance you may provide. Thank you for your time and have a great day!
