magento升级-1.4至1.8

Question

我试过升级，我从1.4.1 成功升级到1.4.2，但前端停止工作。另外，phpmyadmin完全停止。

以下是我的错误登录/opt/lamp/logs。

有谁知道究竟在哪里寻找什么导致这个大日志中的错误？

Answer 1

首先，有一个MySQL错误，服务器已经走了......你应该先检查一下，如果Web服务器可以访问数据库服务器。

第二件事情是当您执行更新（特别是主版本升级）时，请确保将主题和包切换回默认的magento版本，因为layoutchanges会导致奇怪的错误消息或空白页。希望这不是在高效的网站上完成的;）

然后我会清除整个缓存。如果您无权访问后端，只需删除/ docroot/var/cache /下的所有文件和文件夹，并在清除browsercache后重新加载页面。

如果这没有帮助看看是否显示任何前端错误。如果没有，只显示一个空白页面，或只是页面的一部分，其余部分为空白，在php和magento中启用前端错误报告是非常有益的。

那么你应该始终把你的magentolog看看在发现/文档根目录的/ var /日志...特别是exception.log和SYSTEM.LOG可以包含一堆有用的东西......

如果您需要更多的帮助，发送一些更多的信息。
