Do you have the CloudFlare WordPress plugin installed?
All requests are going to appear to come from our IPs (we're a reverse proxy) without something to restore the visitor IP. You do want to make sure requests from CloudFlare's IPs aren't being restricted in any way, as this could actually affect visitors getting to your site.
