I have prepared a Facebook login for an application installed in page, the problem is when I click on the "login" button on the page it redirect to a blank white page, without connecting, but when i open the app with the direct link "https://example.com/my-app", the login is working good without any problems and the user keep being connected after approving the app;
I am working with :
- codeigniter 3.0
- Facebook PHP SDK v4
- PHP 5.4
- Facebook Scope : public_profile, email
Add
target="_top"
to your login link in the iframe to make it redirect to the login page in the top window instance.
