Cannot eliminate canvas page in facebook app

I have set a canvas page, and now, my facebook app page goes to a horrible place: http://apps.facebook.com/hificorder/?ref=ts

whereas it is supposed to go to: http://www.facebook.com/apps/application.php?id=123018831077733

So, set the canvas page to the latter link...right? WRONG....when you do so, it causes an error. Set the canvas page to nothing??? FB does not allow. What do I do???

FYI, when you search for "HiFiCorder" in the normal facebook search, the canvas page is w开发者_如何学Chat comes up...this is horrible, please help.

Your canvas URL should point to your app hosted on YOUR server, it's the landing page to your application on facebook.

While the Facebook Application page is a page hosted by facebook which is totally different.

First of all, it's a good Idea to set a canvas page, for example:

Site URL: http://mydomain.com/fb_app/
Canvas Page: http://apps.facebook.com/fb_app/
Canvas URL: http://mydomain.com/fb_app/canvas/

So on your server, the structure would be something like:

www
   |
    - fb_app
            |
             - app_structure
                            |
                             - ..etc
             - canvas
                     |
                      - index.php // your canvas landing page

EDIT:
So based on your comment, you want your canvas page to act as the Facebook Application page?
then just in your canvas page add this line:

<script>window.top.location = "http://www.facebook.com/apps/application.php?id=123018831077733"</script>

You need to set the canvas link to nothing, this is allowed when you set the app URL to something.
