Email verification problems

I'm having trouble with email verification for form fills. I received the verification email with no issue, but when I follow the "Yes it's me" link, I get a 404 page. The URL doesn't look right, there's a double slash after the base like: https://au.opencitiesplanner.bentley.com//... 

I've disabled the need for email verification for now, but would like to get it working.
