Menus Stopped Working on Mobile Browsers

Hi: I purchased your Catch Responsive Pro them on March 31, 2015. I installed it on my travel site http://www.puertoricobygps.com and it worked perfectly until the latest update. This site also uses a plugin called UberMenu. After the latest update my menus stopped working on mobile browsers. This is a serious problem because most of my visitors actually come from smartphones. I tried accessing the site from my iPhone 5. I haven't tried from an Android phone because I don't have one.
