Yesterday we launched our new authentication system that adds a ton of new security features when making requests to our API. That means your account is safer and we have more tools for dealing with cheaters.
If you're having trouble loading pages that use the API (forums, wardrobe, achievements) try logging out and logging back in, or logging in on new.subeta.net.
Just came back recently after a long hiatus. I've logged in and out countless times and also logged in on New Subeta, but images still won't load on the site for me, and I can't edit any of my profile info, like email address, gender, or name. :c Using Chrome.
