WooCommerce自定义支付网关插件未在结账页显示求助

我为WooCommerce开发了一款自定义支付网关插件，插件激活无任何报错，调试日志显示网关类已完成注册与初始化，但该支付方式并未在WooCommerce结账页面显示，页面仅提示“无可用支付方式”。

}

已尝试操作 #

• 确认WooCommerce已激活；
• 验证插件激活无报错；
• 查看WordPress调试日志，显示WC_Simple_Noob_Pay_Gateway类已注册并初始化。

结果对比 #

预期结果：“Noob Payment”支付方式应在WooCommerce结账页显示为可选支付选项。
实际结果：结账页显示提示信息：“无可用支付方式。这可能是我们的错误。如果您需要帮助下单，请联系我们。”

恳请帮助解决此问题，谢谢！
