Hi

I am using booster for woo-commerce and the function for adding paypal fee. The problem i have is, it not updating the cart total.

Having this function with other website, where I have other theme, there is no problem, and all is working fine.

I mention the cart total, when a customer buy a tour, it showing 7% paypal fees, but it not add in the cart total.

I updated Your theme already, but still no calculating the paypal fees in it. Using another theme, there is no problem.

Regards,
Simon
