Given URL is not allowed by the Application configuration

I am trying to create facebook sign-in page according to this tutorial. I only changed the two lines

appId      : '370675846382420', // App ID
channelUrl : '//http://bp.php5.cz/channel.html', // Channel File

and I get the following error

Given URL is not allowed by the Application configuration.: One or more of the given URLs is not allowed by the App's settings. It must match the Website URL or Canvas URL, or the domain must be a subdomain of one of the App's domains.

What might be the problem?

Solution 1:

The problem is that whatever url you are currently hosting your app is not setup in your Application configuration. Go to your app settings and ensure the urls are matching.

Updated

Steps:

1. Go to 'Basic' settings for your app
2. Select 'Add Platform'
3. Select 'Website'
4. Put your website URL under 'Site URL'

Solution 2:

This can also happen when the redirect_uri submitted with the https://www.facebook.com/dialog/oauth request is not present in the list of Valid OAuth redirect URIs under:

• Settings >> Advanced >> Security

After much trial and error, when I added the redirect_uri that I was using (https://www.facebook.com/connect/login_success.html in my case), I suddenly got to the step past this error.

Solution 3:

The above answers are right, but you have to make sure you input right URL.

You have to go to: https://developers.facebook.com/apps

1. Select your app
2. Click settings
3. Enter contact email (for publishing)
4. Click on +add platform
5. Add your platform (probably WEB)
6. Enter site URL

You have two choices to enter: http://www.example.com or http://example.com

Your app will work only with one of them. In order to make sure your visitors will use your desired url, use .htaccess on your domain.

Here's good tutorial on that: http://eppand.com/redirect-www-to-non-www-with-htaccess-file/

Enjoy!
