Internet explorer big problem!

Hi,

I found a big mistake that i have lost alot of customers on. I need this to be fixed ASAP. Its a mistake that shouldnt be happening.

The problem is that boost sales makes it impossible to order on the Internet Explorer browser. The plugin makes the freight options keep loading forever on Internet Explorer. here is an image of what i mean – https://prnt.sc/o736ba

You can get this bug by doing this:

Go the the shop, put something in the basket and go to the checkout page and look for your self. Remember to be on the internet explorer browser!

I have lost several customers because of this without realising it. They called and said that my website was slow, which it is not. This is what they meant by slow.
