theme won't work on iphones!

I have the Twenty Fourteen theme on my site, themissinformation.com, however it won’t work on iphones even though it’s supposed to be optimized for mobile. It works on ipads and tablets but not the iPhone, even with the use of plugins. Please help! I’ve tried everything I can to try and get the site to come up, but it just shows up as “site not found.”

Thanks in advance 🙂
