Delete browser cache and also cookies. A local session is either using cookies, or local storage on more modern browsers, and if those mismatch to what the website expects, you won't be able to log in.
Unfortunately, you'll have to re-login after doing that.

(Huh, I did learn something in those web programming classes.)
