IDs

Hi I installed this plug in but I’m having difficulty using it, when I tested it there is no QR code that appears just an empty box that says QR code at the top. I’m not sure which ID numbers I am supposed to use in the “application ID” and the “merchant ID” and the key number please help me i’m so confused

我们在wp上的wechatpay界面设置好了收款账户名和密码，然后自己新增了一个产品用来test，价格为0.01$,点击购买后付款页面的二维码不显示，怎么解决？是不是我们的收款账户设置有问题？
