My php error log is full of these entries. The theme functions has references to get_car_url and it clearly states it needs to be updated. I just paid for this theme and requested twice to have this issue resolved.

The WC_Cart::get_cart_url function is deprecated since version 2.5. Replace with wc_get_cart_url.

add_to_cart_fragments is deprecated since version 3.0.0! Use woocommerce_add_to_cart_fragments instead.
I would like to get these errors resolved, the function calls in your theme are depreciated. I asked for help for this and you wanted to gain access to my server, I just want you to fix your code. Is this not something you can do for your paying clients?
