Woocommerce PDF Product Voucher query

Hi,

Looking at the docs here: https://woocommerce.com/document/woocommerce-pdf-product-vouchers/#section-22, it says:

Security plugins: PDF Product Vouchers must access the HTML generated for each voucher to convert it to a PDF. Some security plugins, like WordFence or iThemes Security, can block this and should be disabled or reconfigured to permit this access.

As I am considering purchasing the Woocommerce PDF Product Vouchers plugin and I use Wordfence already, is there a Wordfence setting that can be changed that would allow PDF vouchers to be generated?

Many thanks.
