I have a online food ordering website https://combonation.net with WooCommerce installed. My customers are facing the following problem:
1) They go to my site and click on any menu
2) They select Ala Carte or Combo and Veg or Non Veg
3) When they select any item, the cart appears as (1).Also notice the link in the address bar.. Quite Weird
4) Next when they click on browser back button, the item auto increments itself. Same happens when they click the browser forward button. This happens on all browsers

Kindly help me fixing this issue.

Thanks
