Thanks so much for the clear reply.
Hi Rajesh.
Thanks for coming back to me. Yes, PayPal is working for all other countries, but it’s not showing for South Africa. If I use a VPN to access the site from South Africa, it is not showing.
I’m also having a fatal error with this plugin when I try to use Divi theme builder. When I deactivate the Pre-order plugin it is fine, so the problem must be with the plugin, not the theme.
