从昨天开始，我已经开始遇到结账问题，我花了一整天时间与客户联系并做退款。我使用1.7.0.2和paypal web payment pro。直到昨天，一切都运作良好，大约2年，我们开始让很多客户收取双倍，三倍甚至3/4/5的费用。这似乎是因为他们没有得到确认，所以重新处理订单和paypal继续收费。有些人一直持续到订单通过，其他人从来没有让它工作，我们只知道它，因为我们收到了PayPal付款。
我自己尝试过检测结账，但只有在使用信用卡时才会失败，贝宝付款工作正常。当我进入最后的流程订单阶段（最后阶段）时，我点击按钮，它只是回到第一阶段，产品仍在购物车中。我的客户报告发生了同样的事情。
在exception.log中，我从昨天开始收到以下错误：

paypal日志显示响应为[RESPMSG] =＆gt;已批准（因此付款）
订单大部分都不会显示在magento中，除非该过程在一段时间后工作（我根本无法工作，但有些客户已经完成订单然后才能运行，但他们通常会多次付款） 每次付款时，无论订单是否创建，订单号都会增加1 - 正确的订单号在paypal中显示为发票ID。
不确定是否相关/相关，但也有很多以下错误（虽然这是在结帐问题之前发生的方式：

真的需要一些帮助，因为我不得不关闭我的网站的信用卡处理，这将花费我很多，这是我的主要收入来源。
不确定格式对不起发生了什么，不能让它出来不同抱歉而且我太忙了，无法发送尝试的年龄。
