I just had to change my template due to loss of certain functions on mobile. I have regained the functions but now, if someone adds an item to the shopping cart, the screen goes white like there is a huge blank header. If you scroll down, you can see a portion of the screen go by as you scroll.
If you remove contents from the cart, everything is normal.
Please give it a try to see what I'm trying to describe. Put a kite in the cart on a phone (android at the moment) and see what happens. https://www.hardwaterkiter.com/
Thanks.
