How can I change the link of the Logout menu option

Hello guys,

Something wrong is happening, I log in normally in Coursepress but when I click logout I'm being redirected to http://courses.nativeportuguese.co/student-login/ which gives me an error ¨Page not found¨

Since I'm using Membermouse for memberships I need to change this Logout link (core page) to http://courses.nativeportuguese.co/logout-1

How can I do that?

Thanks for your help.
