问题描述
我犯了一个严重错误，我似乎无法撤消它！
一个客户突然想要一个网站(被搁置)尽快上线. 解决简单的问题，我只是删除了cPanel中的重定向.或者我以为… 然后我看到，该特定站点的重定向是对另一个域上通用404站点的301永久重定向. 注意:我们有经销商解决方案，并且在同一cPanel中将多个站点作为子域托管.
我删除了cPanel中的重定向，但该站点仍重定向到另一个域.我等了一个小时，然后是2-但没有成功.
仅主网址被重定向: customersite.dk-> developer-dd.dk/404
子页面正常工作: customersite.dk/subpage/
然后我等不及了，我在cPanel中创建了一个新的302重定向，将 customersite.dk 重定向到 customersite.dk/fakefrontpage/ 这样做是有效的，因为利用了这一事实，子页面可以正常工作，但是我认为这是一个临时解决方法，直到我已经解决了真正的问题.
我认为/希望与此相关的一个问题是，facebook共享调试器似乎无法获取该站点.因此，客户无法通过图像，标题和元文本在社交网站上共享该网站.
我该怎么办? 如何撤消已经使用了几个月的301重定向的影响? 如果实际上是问题所在? 它也有SEO分叉吗?
我将.htaccess文件粘贴到此处:(我用 customersite 替换了真实网址)

推荐答案
您应始终使用302重定向进行测试.切勿在生产服务器上使用301重定向进行测试.除了清除缓存，别无其他方法.使用重定向规则时，请记住这一点.
警告:如果您确实使用301重定向，并且有许多用户访问您的网站.您必须礼貌地要求他们在重定向到达的页面上清除其缓存.
