Redirection error with the button "Register an Account Today"

Hello: I had a strange error. On the community page (main) when you offer to login and if you have an account, create one, if you press the button "create an account" this redirects to http://www.mysite./DASHBOARD/registration instead of http://www.mysite. / registration. If you manually click the URL there are no problems with the registration page. It is the button that fails. I have made a mistake in configuring a parameter? Is it an easysocial bug?

Thanks for your help and your time.
