Have you activated your account ? You should have received an email from noreply+evrything@freeflarum.com with a link.
You need to click the link before login in.
Once done, try to login, it will says “Oops! Something went wrong. Please reload the page and try again.”. You need to reload the page and you’ll be connected.
However, I don’t know why this error message appears, maybe an extension or some settings caused this.
