On my website I use a subscription to the WooCommerce plugin, where I have a registration fee ($ 10 ish), and then a free trial for 7 days. Then we charge a client about $ 55 for the next product. I use a plugin called Smartsend, which is a logical plugin for Danish media.
When I order a product from my online store, I get an error message:
"invalid duplicate delivery method"
despite the fact that everything looks perfectly tuned in the system.
When ordering $ 55, I can print the shortcut on my printer, but with the registration fee of $ 10 I can not, because I get this notification.
I hope you can help.
