Interface won't show more than a screen full of info. Anything below that level, which I would normally have to scroll down to is inaccessible. I've tried reloading it several times and still can't see anything below the screen shot. This happens frequently, it's just more persistent today.
This is a common issue when Facebook is pushing code or making changes. ***TECHNICAL REASON*** For Facebook, Zombie Slayer is in an iframe, Facebook provides code that dynamically resizes the iframe to fit content of the game, if for whatever reason Facebook cannot provide the code the iframe will not be resized and content will be cutoff. Clearing cache of the browser will sometimes help or else waiting an hour or so for Facebook to provide a new version of the code required to re-size the iframe.
To add to what Kendall said, instead of refreshing the page, click on the Facebook logo to go back to your FB page, then click back into the ZS app. I have to do this for MW from time to time.
