Major problems on our site, we've found that no users can register on our site, the last successful registration was 11 days ago. Seems to coincide with last 7.5 upgrade. Checked by creating a demo site, enabling anon registration, users can't register.
User just keeps getting the registration page back with errors saying 'email address is required' even though it's filled in, same with first name, last name, and custom fields. Even erroring on 'show as online' though that's hidden from the registration form.
This is causing major embarrassment for us :(
