Sub menus not working in catch evolution

After I added a plugin called autoptimize in wordpress, it broke all the sub menus in catch evolution. They show up when I hover the main menu, but you can't scroll or click, and the third menus don't show up at all. The website is greenbeautycosmetics.com. I have deleted the faulty plugin, but the sub menus still don't work. I also got my host to re-instate an earlier version of the website, but that didn't work either. I also tried to re-install the same version of catch evolution again. Sub menus are still not working. I make all my money from this website, so I need an answer urgently. Thanks
