Woocommerce checkout button problem

Good evening!
I have a problem: in Woocommerce 2.0.2.0 my checkout button doesn’t work. When I push the button I have just two points spinning round endlessly.
This problem arose when I had imported my site from denwer to server.
Please, help me to solve it.

P.S.
I’ve tried this: (http://docs.woothemes.com/document/endless-loadingspinner-on-the-checkout-page/) but it didn’t help at all.
