My team is in charge of some difficulties with an app on Facebook. We believe this occurred some error in loading the iframe. We discovered this error through Firebug:
Load denied by X-Frame-Options: https://www.facebook.com/dialog/oauth?client_id=140656472747871&redirect_uri=https%3A%2F%2Fnuvemapps.com.br%2Fci%2Fncupons%2Fhome%2F%3Ffb_source%3Dsearch%26ref%3Dts%26fref%3Dts&state=32e667a3645c047d751d20811d49ef6b&req_perms=email%2C+publish_steram%2C+manage_pages does not permit framing.
This happens mainly with people who have not allowed the app, so we do not know specifically where this problem is starting. We still have three possible causes left:
- Server Configuration
- Problem with our coding
- Or in our setup facebook app dev
Can anyone help in identifying this error?
Here is the link to the app: https://apps.facebook.com/cupomigo
I got the same issue, and it got fixed, when i used target="_top" for the link , and it is now working perfectly.
Thank you

I believe there is not much we can do but wait for a fix. Have the same issue with the "FB Share" plugin.
Use this line given below instead of header() function.
echo "<script>window.top.location = 'https://apps.facebook.com/yourappnamespace/';</script>";
