Contact form on form submission redirects to index.twig I've run into issues with the contact form plugin - https://github.com/craftcms/contact-form/issues/156 - Any ideas
I inspected your form, and the redirect value is 45e4c422dc3ef7c10d24f04e10a42c07affd1f5456fb253747b332aed6481678thanks.

Perhaps try being more explicit with your redirect, something like: {{ redirectInput(siteUrl ~ 'thanks') }}
