continue button not working to next section

I’m a newbie to magento. The fact is that I’ve installed magento 1.9.3.10 through softaculous on new.bbymotors.ro, installed and update the website, and even check that all the functionality are working properly. Yesterday, I’ve asked my IT guy to move the website new.bbymotors.ro so that it redirrects to bbymotors.ro. After this move, the customers can’t place the orders as the continue button under shipping is not moving forward. Please help!!!! I’ve worked at this website for the last 3 weeks and my IT guy can’t solve it as it doesn’t know what to do…

address of the website is http://bbymotors.ro

Thank you in advance
