::UPDATE:: LINKS DO NOT EXIST ANYMORE!
Very strange indeed, this is definitely a bug! I did a test with app_id from another application and it worked. See for yourself:
https://apps.megalopes.com/megabraziltv/test.php (app_id correct)
https://apps.megalopes.com/megabraziltv/test2.php (app_id from another application)
---/---
I found several people with the same question and all the answers are equal: Site URL is not same as REQUEST_URI (Redirecting URL)
My app setting are:
Secure Page Tab URL: apps.megalopes.com/megabraziltv/...
App Domain: megalopes.com
code:
<div id="fb-root"></div>
<script src="http://connect.facebook.net/pt_BR/all.js">
</script>
<script>
FB.init({
appId:'123456789', cookie:true,
status:true, xfbml:true
});
FB.ui({ method: 'apprequests',
message: 'Here is a new Requests dialog...'});
</script>
This simple code is not redirecting to any other url. I tested on the js console getting the same results. Sometimes works and sometimes I get this error message:
API Error Code: 191 API Error Description: The specified URL is not owned by the application Error Message: redirect_uri is not owned by the application.
Regardless of being page tab or canvas, you must identify the website Site URL in https://developers.facebook.com/apps
How I fixed:
App Domain: megalopes.com (domain)
Site URL: / Secure Canvas URL: / Secure Page Tab URL: https://www.megalopes.com (subdomain)
I think I have run into something similar before.
In the summary page of your app ensure both the Secure Canvas URL and Page Tab URL are populated.
The URL in my redirect_uri should have "http://" in the beginning. It was missing the protocol information, thus leading Facebook not to recognize my website and throw this annoying 191 error. I finally found out after one hour pulling the hair I (still) have left.
You have to create a channel page, which allows "cross domain communication in certain browsers"
This is an html page (saying /channel.html) on your server, which only contains :
<script src="//connect.facebook.net/en_US/all.js"></script>
And make the Javascript SDK aware of it :
FB.init({
appId: 'xxxxxx',
cookie: true,
channelUrl: location.protocol + '//' + location.host + '/channel.html'
});
More about this :
It's because of domain URL that you mentioned in facebook's mistake. Domain URL wont be like www.site.com
Update your domain url like subdomain.site.com.
Now it surely work.
