I noticed this earlier, what happened was that if you go to the-coli.com without www it only sets cookies for www . the-coli.com when you login and then redirects you to the home page without the www
right now when I go to the-coli.com it redirects to www. the-coli .com so something must have changed / been fixed
in any case, enforce either a required www or no-www by redirecting users
