Problem with Search in the Store empties the basket

[[email protected]]

Hello how are you?
I do not know much about PHP, I am not a programmer and in my store installed at www.shopdepesca.com.ar/tienda/ when I use the product search box it empties my cart.
The problem is that if there are products in the basket and the customer executes a special search such as (See Link) the basket remains empty:
https://shopdepesca.com.ar/tienda/advanced_search_result.php?keywords=titan+bg
With an old Firefox everything is normal but with updated browsers this failure occurs.
Could someone guide me? Thanks
