I've had the same issue (and others) since the Terms & Conditions glitch as of last night.
I can't get search results, can't access individual apps, even when directly linked to them (i.e. from an in-App Store list such as New & Noteworthy, a third party app such as AppZapp or a website) and can't bring up list of purchased apps.
Contacted Apple - got a response that the App Store is working & that it may be a Wifi issue for me. Yeah, right. They asked for screenshots, so I sent back my blank screen results (along with full wifi strength icon).
Force quitting App Store, resetting phone did nothing.
