我已经创建了一个ccavenue帐户，并且配置如下所示，
{"ccAvenueSubmitUrl":"https://www.ccavenue.com/shopzone/cc_details.jsp","Merchant_Id":"M_pet26783_26783","working key":"7hvem666hlxv6yknpk0pcytmo5owxdu3","confirmation":"true","confirmation message":"You are about to be redirected to an external payment gateway for processing your payment. This is a highly secure and trusted site. Are you sure you want to continue?"}
现在，我更改了ccvavenue帐户，创建了新的商人ID和工作密钥。 我配置了新的商户ID和工作密钥，但是到达了付款选项，就会生成两个错误错误90和错误说明：
必填+参数+是+缺失+或+无效+会话。％3CB + style％3D％22color％3Ared％22％3EKindly + clear + cache + of +浏览器+并+重新启动+您的交易+％ 3C％2FB％3E
。该配置使用了Yii框架version 1。现在我是yii1的新手。有人可以帮忙得到这个
