Question

I've downloaded an opencart installation in my local server in order to use it as a test and i'm not able to view the site. When i use the default htaccess file the browser returns a 500 error and when i remove the htaccess file the seo - links do not work. (404)

Any ideas?

My .htaccess file

# 1.To use URL Alias you need to be running apache with mod_rewrite enabled.

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

### 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

.htaccess文件通常对语法非常敏感，任何错误都可能引发http 500错误。错误可以与httpd升级后不支持的语法错误和/或指令相关联。

我建议您逐步测试.htaccess的备份副本，然后从空白文件开始添加一些部分，直到服务器出现错误。

如果有，请考虑从本质上解决问题。

在OpenCart中调试500个服务器错误时要做的第一件事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，您可能需要通过调整 error_reporting ， display_errors 和 log_errors 设置来明确启用它们。你的PHP配置。您也可以直接在主index.php文件中临时更改它们。

一旦您知道确切的错误消息，修复它就是一个简单的过程。

我们在博客文章Server Errors and Blank Pages in OpenCart: Most Common Causes中介绍了一些最常见的OpenCart错误消息，导致500个服务器错误。

我建议不要尝试修复空白页面和500个服务器错误，而无法查看错误日志。这些问题可能是由几乎任何事情引起的，从服务器配置和限制到破坏的OpenCart代码，所以你真的需要知道你正在处理什么。

在您的特定情况下，很可能是由于您的服务器配置禁止将特定规则放在.htaccess文件中引起的。
