::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.
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 :
And make the Javascript SDK aware of it :
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.
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.
