Bitpay no want work on woocommerce, blank page

Hi, I’m a webmaster and I’m having a little problem with your plugin.

I installed bitpay for woocommerce. I installed woocommerce and I added products. Then I created the bitpay account code as you explained in the FAQ. So far so good, I have configured everything perfectly. But when I try to buy a product and choose to pay with bitcoin, you open a blank, white page and do not load anything. I can not understand where I’m wrong. I think I did everything right, I chose livenet. I am an expert I have no difficulty in these things.

But there seems to be a problem of page referencing or similar things.

all other methods work.

Do I have to do some other particular configuration, such as the redirect url?

Thank you
