Error 191 on Facebook, but the URL is configured correctly

Question

I have a problem with redirect_uri, but everything is configured correctly. I left this code alone for a week when it worked fine, took it again today, and this error was unchanged.

This is the application URL in the settings: http://www.shifty.com.br/europa/quemtemboca/app/ https://www.shifty.com.br/europa/quemtemboca/app/

This is the application page: http://www.facebook.com/recifetest/

Sharing worked perfectly, now it has absolutely no changes. Very strange.

Thanks for any help in advance.

Answer 1

This is confirmed as a recent bug (but it should be resolved now).

You can try the following:

1) enter the address in "Website using Facebook Login" => URL of the site

2) fill in the "Application Domains" with your domain. (you cannot save if you skip step 1)
