When collecting a payment on my website through a link to PayPal, I receive a message that there is a fatal error. Is there a conflict between Woocommerce and PayPal that I can correct? Thank you.
I use Woo and PayPal all the time. Fatal error makes me think a server issue and doesn't tell us what or where the problem is. Could be so many things... You can look at WooCommerce > Status to see if there are any issues there to look into.
Make sure all your settings in WooCommerce > Settings > Checkout PayPal Advanced/PayPal tabs are correct. If they are, someone is going to have to interrogate your setup and hosting to determine what the issue may be.
