ADD To CART is freezing

Hi Natasha,

I need urgent help with my ‘add to cart’ stage of booking in woocommerce for my page, it is freezing and won’t let customers add more people or progress to cart !
Please help me urgently with this ..is it a compatability issue with the newest version of woo commerce plug in ?
I need to fix it urgently
I have the latest wordpress upgrade and I use avada theme
Please help with ongoing recommendations on when to update to the latest woocommerce plugin in relation to your plugin as it seems to have happened a few times
much thanks in advance
Alex
