I’m going through the [[https://auth0.com/docs/quickstart/webapp/rails/01-login](https://auth0.com/docs/quickstart/webapp/rails/01-login)]([http://Ruby](http://Ruby) on Rails Auth0 SDK quickstart) and the only thing that isn’t working is the whitelisting of the URL that should be redirected to after a successful logout. I can log in, and the logout link clears the session, but always brings me here and tells me my returnTo parameter is not defined in “Allowed Logout URLs”: ![image](https://global.discourse-cdn.com/auth0/original/3X/5/b/5bce8bc2d51a605df28b02a237f8434ea18fced2.png) except it clearly IS defined and I’ve tried removing the trailing slash and other silly things. What am I missing here? ![image](https://global.discourse-cdn.com/auth0/original/3X/8/a/8ac05b859e4d3a42d82d66802261bc7fd53218a2.png) thank you for any help. I’d really like to get started with auth0 and this trial run is messin with my vibe. 🙂 ---

Hi @pdbradley, welcome to the Auth0 community! Have you tried without the trailing slash? I.e. `http://localhost:3000` ---

@kstrongholte I did, and to no avail. However, I just downloaded the “prefilled” rails app that the tutorial offers (prefilled with my own creds) and…it works. so I must have configured something wrong as I followed the steps. I just went through the one I did by hand and compared it carefully with the pre-filled and I don’t see any difference, but it is there, and I need to pay the price to find it. So at least I know I’m probably the culprit. thanks ---
