Sorry, but the mobile version does not use WordPress best practices. To an extent where it makes plugins unable to run on the page as it does not make use of the wp_head(); nor wp_footer(); functions. Even if you include wp_footer(); in the page, duplicate jQuery problem will start to occur. It's because they hard-code jQuery's loading, which is vastly frowned upon in the WordPress community. The solution is to choose the ProPhoto > Customize > Mobile > use desktop site on mobile devices option. ProPhoto 5 uses jQuery mobile and a gray (generally design-less) site for mobile devices. It's not recommended to use a mobile theme that looks significantly different from the desktop theme. Nowadays the trend and the expected design is about the responsive style.
