title: Facebook tab app page is blank! what am I missing?
body: <p>I have created a 520 px page for FB. I have gone through all of the developers steps. I can see the page from the link. i can see the page from the secure link. copying all of the links from the FB app, they work. I have set up the tab and I see the tab on my FB page. When i click the tab or go directly to the tab, FB is there but it is just white space. I can't see what I am missing. I have loaded, reloaded, cleared cache, etc. I'm sure it's something simple, but I've spent hours searching. thanks.</p>
