For me  it was a missing app domain   Go into the app  and make sure that you have the root of your site set up as an app domain   See screenshot

This is just because of a URL mistake   Whatever website URL is specified should be correct   I mentioned website URL as http   localhost 3000  and domain as localhost  but in my browser I was running http   0 0 0 0 3000    When I ran server as localhost 3000 it solved the problem   As I mentioned  the site URL as localhost Facebook will redirect to the same  if we are running  0 0 0 0 3000  it will rise error that  Given URL is not allowed by the Application configuration

in the facebook App Page  goto the basic tab  find  Website with Facebook Login  Option   you will find Site URL  input there put the full URL   for example http   Mywebsite com MyLogin aspx    this is the URL you can use with the call like If the APP ID is 123456789  https   graph facebook com oauth authorize client id 123456789 amp redirect uri http   Mywebsite MyLogin aspx amp scope publish actions

I fixed this by passing the redirect url to the FacebookRedirectLoginHelper  getAccessToken   in my callback function   Changing from   try            accessToken    helper- gt getAccessToken            to  try            accessToken    helper- gt getAccessToken  fbRedirectUrl           I am developing on a vagrant box  and it seems FacebookRedirectLoginHelper  getCurrentUrl   had issues generating a valid url

UPDATE  To answer the API Error Code  191 The redirect uri should be equal  or relative  to the Site URL      Tip   Use base URLs instead of full URLs pointing to specific pages     NOT RECOMMENDED  For example  if you use www mydomain com fb test html as your Site URL and having www mydomain com fb secondPage html as redirect uri this will give you the 191 error     RECOMMENDED  So instead have your Site URL set to a base URL like  www mydomain com  OR www mydomain com fb      I went through the Facebook Python sample application today  and I was shocked it was stating clearly that you can use http   localhost 8080  as Site URL if you are developing locally      Configure the Site URL  and point it   to your Web Server  If you re   developing locally  you can use   http   localhost 8080    While I was sure you can t do that  based on my own experience  very old test though  it seems that you actually CAN test your Facebook application locally   So I picked up an old application of mine and edited its name  Site URL and Canvas URL  Site URL  http   localhost 80 fblocal   I downloaded the latest Facebook PHP-SDK and threw it in my xampp htdocs fblocal  folder   But I got the same error as yours  I noticed that XAMPP is doing an automatic redirection to http   localhost fblocal  so I changed the setting to simply http   localhost fblocal  and the error was gone BUT I had to remove the application  from privacy settings  and re-install my application and here are the results    After that  asked for the publish stream permission  and I was able to publish to my profile  using the PHP-SDK       user    facebook- gt getUser    if   user        try            post    facebook- gt api   me feed    post   array  message   gt  Hello World  from localhost            catch  FacebookApiException  e            error log  e            user   null            Results

For me it s the Valid OAuth Redirect URIs in Facebook Login Settings  The 191 error is gone once I updated the correct redirect URI

I have noticed also that even if you specify your website under secion - Website With Facebook Login -  Site url as e g   http   example com  but if your App Domains section is empty  and you open website as www example com you will get this error  too  To avoid it in  App Domains  section write example com  that will allow subdomains  like www example com  something example com etc

Something I d like to add  since this is error 191 first question on google   When redirecting to facebook instead of your own site for a signed request  you might experience this error if the user has secure browsing on and your app does redirect to facebook without SSL

I was also facing the same problem when I am using the facebook authentication method  But I rectify that issue with following changes in Facebook api  Apps  gt  gt  My App  gt  gt  Basic     I removed the url which i have given in       App on Facebook  Canvas URLs  I gave site url only in      Website with Facebook Login option   Then i gave that AppId and App Secret in my webpage   So by clicking on login button  It ask for access permissions then it redirect it to give url  Website with Facebook Login
