几个星期前，我发生了服务器崩溃，没有真正的备份，因此必须手动恢复所有内容。其中一件事是Magento商店。我已经恢复了所有文件和数据库，但是现在当我尝试通过结帐流程来测试时我会收到错误。
我可以在退房时点击注册，然后当我点击结帐页面上的“继续”时，我会收到“正在加载下一步”消息，然后在尝试访问saveBilling时Chrome网络检查器中出现某种AJAX错误页。错误列在下面：
Notice: Undefined variable: nameGroupAttribute in /var/www/vhosts/mysite.com/httpdocs/app/code/local/Amasty/Customerattr/Model/Rewrite/Checkout/Type/Onepage.php on line 41

#7 /var/www/vhosts/mysite.com/httpdocs/index.php(85): Mage::run('', 'store')
#8 {main}
我搜索了每一个我能想到并且空洞的词汇组合。这个网站是在我到达这家公司之前设置好的，所以我不知道是否有任何改变是不应该的。我所知道的是，在服务器发生故障之前，该网站正在运行，现在这一部分无法正常工作。
感谢您的帮助！
