The choice of language and buy button does not work

I use 3.0.2.0
Suddenly, the choice of language does not work, nor does the buy button and some other buttons.

for some reason the jquery link is broken
check if it is in catalog/view/javascript/jquery folder
by default is another version of jquery "jquery-2.1.1.min.js" which it is on your server.

Great, thanks! That was the problem!

You’re welcome!
