内部服务器错误 - Opencart

Question

我已经在本地服务器中下载了opencart安装程序，以便将其用作测试并且我无法查看该站点。当我使用默认的htaccess文件时，浏览器返回500错误，当我删除htaccess文件时，seo链接不起作用。 （404）

任何想法？

我的.htaccess文件

# 2. In your opencart directory rename htaccess.txt to .htaccess.

### Additional Settings that may need to be enabled for some servers 
### Uncomment the commands by removing the # sign in front of it. 
### If you get an "Internal Server Error 500" after enabling any of the following settings, restore the # as this means your host doesn't allow that. 

# 1. If your cart only allows you to add one item at a time, it is possible register_globals is on. This may work to disable it: 
# php_flag register_globals off 

# 2. If your cart has magic quotes enabled, This may work to disable it: 
# php_flag magic_quotes_gpc Off 

# 3. Set max upload file size. Most hosts will limit this and not allow it to be overridden but you can try 
# php_value upload_max_filesize 999M 

# 4. set max post size. uncomment this line if you have a lot of product options or are getting errors where forms are not saving all fields 
# php_value post_max_size 999M 

# 5. set max time script can take. uncomment this line if you have a lot of product options or are getting errors where forms are not saving all fields 
# php_value max_execution_time 200

.htaccess文件一般都非常明智的语法，任何故障可以提高一个HTTP 500错误。错误可能与httpd升级后不支持的语法错误和/或指令有关。

我建议你逐步测试.htaccess的备份副本，并从空白文件开始添加一些部分，直到你的服务器产生错误。

当你有它时，考虑自然解决问题。

在OpenCart中调试500个服务器错误时要做的第一件事就是查看服务器的错误日志并找到确切的错误消息。

如果没有任何，你可能需要在你的PHP配置调整使用error_reporting，的display_errors和log_errors设置中明确启用它们。您也可以直接在主index.php文件中临时更改它们。

一旦你知道确切的错误信息，修复它是一个简单的过程。

我们已经介绍了一些最常见的OpenCart错误消息，在我们的博客文章中导致500个服务器错误：Server Errors and Blank Pages in OpenCart: Most Common Causes。

我建议不要试图修复空白页面和500服务器错误，而不能查看错误日志。这些问题可能是由您的服务器配置和限制破坏OpenCart代码的几乎任何东西引起的，因此您确实需要知道您正在处理的是什么。

在您的特殊情况下，很可能是由于您的服务器配置禁止将特定规则放置在.htaccess文件中。
