Hi!
Just installed the plugin, set everything up, simulated a purchase.
Now everytime I try to download or preview an invoice it shows me the 500 error page as you can see in screenshots.

Hello Ricardo,

What PHP version are you using? Please send us a WooCommerce system status. Here’s a screenshot showing how to get it.
