问题出现在目录搜索中，当我在主页上搜索名为“搜索整个商店”的搜索框中输入任何产品时。它给出了“处理您的请求时出错”，并出现以下错误

答案 0 :(得分：-1)
有些东西在某处混淆了。我要么说某人做了主题没有预期的修改，通过Magento Admin的某个商店或类别配置，或者evoque主题中的错误。
Evoque是一个高级主题，你可以get support from the authors here。
我们可以从错误报告中看到失败点是文件C:\wamp\www\shop\app\design\frontend\evoque\default\template\catalog\product\list\toolbar.phtml
要修复此故障，您应检查该文件，并在执行第111行之前测试空类别，或者进行一些分析以找出特定用例的类别为NULL的原因。
可以在这里粘贴toolbar.phtml的第101到121行，你可以得到一个解决方案（包括创建一个更健壮的toolbar.phtml的自定义子主题）但我建议在official theme support site提出罚单。
