We've created a Facebook page which we want to open up in a Facebook tab. The url is: https://apps.facebook.com/taggifi_android
The web page is located at: http://www.taggifi.com/android-signup/
The error we are getting in Chrome's dev console is:
Refused to display 'https://taggifi.com/android-signup/' in a frame because it set 'X-Frame-Options' to 'SAMEORIGIN'.
There's a number of solutions that tell us to modify the X-Frame-Options. We've done that locally on the page by modifying the options to GOFORIT as per this Stack overflow question.
We've pulled out all javascript to see if any external references were causing issues, they weren't. We also modified the form POST url to see if that was causing the issue, since it's posting to campaign monitor. That didn't help either. What we can see in the dev console however is that the page appears to be hitting a 403 error on a POST. Hence we tried modifying the url.
Does anyone have any other solutions as we're all out of ideas and other solutions on here seem to have unrelated functionality? This is a pretty basic page that posts a form to campaign monitor.
We're coding in Python.
