Mobile Not Using Theme After Hacking Attack

A client’s site was hacked, causing all of the mobile traffic to be redirected to porn sites. When I reviewed the htaccess file I found the redirect code, and replaced all of the code on that page with the standard WordPress htaccess code. Mobile traffic is no longer directed off the site, but unfortunately the site looks completely unformatted when I visit it with my Android phone. It looks fine when I visit the site with my laptop, but on the phone it does not appear to be using the theme at all. Any advice on how to repair the site so the theme will again be used for mobile devices? If you want to see for yourself, the site is located at https://www.cacme.org. Thanks!
