This is a known issue and we are working on it currently There was a new update implemented that disables the create button if you've already clicked it to prevent duplicate horses from being uploaded or entered into shows twice or more, which happens if people click very fast in a short amount of time. It is supposed to go away and allow the button to be pressed again when the horse is successfully uploaded and you see its page, but if it doesn't actually load to that page then the create button remains disabled and it appears to be frozen/broken. We're modifying this so that it's only disabled for a few seconds, rather than when the page refreshes. This fix will be implemented today!
