I am not sure when this happen, but today I have noticed, that button is missing so user can't proceed to checkout. It is urgent please.

Hello,

Your website seems to have a lot of JQuery error message, using the JqueryEasy extension will probably help you :
extensions.joomla.org/extension/jquery-easy/
