When you set up Facebook Login or change it and have made a mistake in the setup, you will get an error message when signing in or login in with Facebook. There are different error messages depending on what the issue is.

In this article, we show you how to solve the error message URL blocked: This redirect failed because the redirect URI is not white-listed in the app's client OAuth settings. Make sure that the client and web OAuth logins are on and add all your app domains as valid OAuth redirect URIs.

What is causing the error?

The error message displays because a field in the Facebook Login app has invalid information.

The error message tells what the issue is: "URL blocked: This redirect failed because the redirect URI is not white-listed in the app's client OAuth settings. Make sure that the client and web OAuth logins are on and add all your app domains as valid OAuth redirect URIs."

This is easily fixed.

1. Go to https://developers.facebook.com/.
2. Log in
3. Go to the app you created for your marketplace.
   
4. Click on Facebook Login

The field you need to edit is Valid OAuth redirect URIs.

Fixing the error:

1. In the "Valid OAuth redirect URIs" field add your marketplace address followed by /store/account/social?network=Facebook e.g. https://www.mystore.com/store/account/social?network=Facebook
