never mind. I solved my issue.
i have narrowed down where my problem is:
one is here
if(e||n(".woocommerce-error, .woocommerce-message, .woocommerce-info").remove(),0===r.length){
if(n(".woocommerce-checkout").length)return void window.location.reload();
and the other is here
n(document.body).trigger("updated_wc_div")}
else window.location.reload()},
I wonder if I can just delete that line with “else” and see who freaks out!!!
Thanks for your reply. I went thru that article and disabled all plugins except woocommerce. The situation persists. it appears to me that woocommerce itself maybe the cuplrit here! Any input of text in the coupon code box or click of mouse to adjust quantity of product triggers the refresh which precisely happen every 10 seconds!
