404 Error on redirect

Gotcha. I'm still really not sure why the redirection URL is coming up as "my-profile" in any case. With that option disabled, it should simply be the "/login-user" page, which is what the user is on. If you look at the code on that page, you'll see a return variable in the login forms with a value of "L2xvZ2luLXBhZ2U=". If you do a PHP base64_decode on that, it's actually trying to return the user (properly) to the "login-user" page. So, something else is detecting the user is on the login-user page when they're already logged in, and redirecting them to "my-profile". That's not JFBConnect, but hopefully helps you investigate more if you want to fix it.

Thanks for the info, and good luck!
