We have checked your site and found few issues in WooCommerce plugin. We want to check by disabling all plugin and re-install the WoOCommerce. If you allow us to do that then we will start checking. Please let me know as soon as possible.
I am really sorry for being late. Our developers are in the weekend now. They will be available from tomorrow and within tomorrow you will get the solution. Please keep patience. I know it is really important for you.
