Migrated V11 site to V13.1, just get Page not Found. All views are in place and correctly set in doctypes. The only error I get in the BO is "Microsoft.AspNetCore.Antiforgery.AntiforgeryValidationException: The antiforgery token could not be decrypted." Can't work it out.
@Craig100 I have a very vague recollection of someone either on here or Twitter pointing to clearing out cookies fixing an exception like that after an upgrade. But I don't think that explains the 404s coming up!
@CodeBunTes It might have been me on Discord, but I've tried that with no luck :(
