Unable To Create Furry Paws Account

I recently attempted to create an account on the Furry Paws website but was unable to. I'm using an IPhone XR that's running IOS 12.4 and tried to make the account in Safari. I entered all the info needed, read through the terms and excepted them as well as varifying that I'm not a robot. But after I did all that, nothing happened. It just loaded the same page with the terms and both boxes unchecked. Can someone please tell me what the heck is going on?
