Facebook OAuth redirect_uri to page tab error

I am following this tutorial http://developers.facebook.com/docs/appsonfacebook/tutorial/ and specifically at this part of code

 $app_id = "YOUR_APP_ID";
 
 $canvas_page = "YOUR_CANVAS_PAGE_URL";

 $auth_url = "http://www.facebook.com/dialog/oauth?client_id=" 
        . $app_id . "&redirect_uri=" . urlencode($canvas_page);

When I enter $canvas_page as

$canvas_page = "http://www.facebook.com/PAGE_NAME/app_APP_ID/"

I get an "Error occured. Try again Later"

If I enter Canvas Page Url instead, it shows the canvas page correctly but I do not want that.

I am sure that it was working last week, so I do not know what is wrong now.

What was previously working was this

$canvas_page="http://www.facebook.com/pages/PAGE_NAME/PAGE_ID?sk=app_APP_ID"

but since I changed the app to a namespace I had to do something like this:

$canvas_page="http://apps.facebook.com/APP_NAMESPACE/"

and it now shows up correctly without error

For me the problem was the GET request, somehow it seems facebook asks for the GET parameter, I will show you what I mean:

I had this: 

uri = "http://www.facebook.com/pagename/app_appId";

When I changed it to the below it started working:

uri = "http://www.facebook.com/pagename/?sk=app_appId";

Hope this helps someone as it helped me.

In the app settings, try put TAB URL in:

app on facebook -> canvas URL

In the secure URL too

Put in here WITH Slash at the end, BUT in your REDIRECTION put WITHOUT slash at the end.

According to the docs, this should work - https://developers.facebook.com/docs/authentication/pagetab/

What won't work is redirecting directly from Canvas App -> Auth Dialog -> Page Tab but Page Tab -> Auth Dialog -> Page Tab should work fine with that documentation
