Just upgraded a site to ZC 1.5.8a. Most everything is working, but the ReCaptcha is off screen to the left on the contact page on iPhones and probably other mobile devices. See https://macbrud.com/index.php?main_page=contact_us. How to get it to center?

Not sure what version of the plugin I'm using (where do I look for that?). Is there a recent version which solves this problem?
