如何调试、排错zen cart网店（出现空白页面）？

[Jack]

把/includes/languages/english/email_extras.php 这个文件用源版的文件替换一次吧
可以到这里下载：http://www.zen-cart.cn/forum/code.php?mode=view&d=78&f=33

[easysnail]

用原版文件替换了还是一样，请问还有什么方法能够解决吗？thx

[easysnail]

问题终于解决了，去了zencart英文站下载了Debug Error Logging Utility，检查Log文件，发现原来是english.php出了问题，已经修改好了

[zhang-jiayu]

我是全新的新手，请问我的首页整个模板都在屏幕的左边，我该怎么修改啊?(我是买的模板）

页面出现下面的错误提示后我没法登录后台了，而且后台好像都变成英文的了

[Jack]

你的数据表counter_history中少了startdate字段，检查下数据库怎么了？这是zencart安装后就应该有的字段。

[abcd110]

老大，我调试的全部是Notice，没有一个是致命的错误，可是为什么我打开英文好好的， 点一进中文就是空白页，而且在刷新，还是空白页， 关闭浏览器，重新输入域名，又可以打开了， 不过在点中文，又出现空白页了，我查了下说是什么bom的问题， 是不是不能直接用文本进行修改php文件的，只能用dw等工具来开啊！

[abcd110]

jack老大，我点我中文的页面出现提示了

\includes\languages\schinese.php 这个文件第26行有错误
