If you clear out the browser history or if need be reset the browser, that should take care of this message.  Some browsers, especially Safari, try to remember previous urls and sometimes try to redirect from one webpage to another. 

The sign in page for Maumee should be: https://samegoal.com/iep/a/maumeek12.org and shouldn't be
https://samegoal.org/iep/login  

If you are able to get on the https://samegoal.org/iep/login page, then you'll get redirected to https://samegoal.com/iep/login page and then need to use the full e-mail as the username. 

It is better to go to: https://samegoal.com/iep/a/maumeek12.org
