Membership / Log-in Redirect NOT working

Rather frustrated with what seems like should be a no-brainer..

I have installed both Membership and the Login Redirect plugins. I have the settings to redirect to: (this is the home page where I am building the site)

But instead, it redirects to: (a page that doesn't exist)

Then, when I try to go back to the page that it should redirect to, it shows that the user is NOT logged in. However, when you click on a different page, it shows that you are still logged in.

I have tried the redirect settings in both "general > settings" as well as on the membership log in widget itself.

What the heck could I be doing wrong? Seems like it should be a no-brainer. :disappointed:

Thank you very much for any help.
