Nginx 错误：'try_files' 指令使用错误

This error occurs when the 'try_files' directive is used in a location where it is not allowed in the Nginx configuration file.

To fix this error, you need to move the 'try_files' directive to a valid location. The 'try_files' directive should only be used within a 'location' block.

For example, you can move the 'try_files' directive to a location block like this:

location / {
    try_files $uri $uri/ /index.php?$query_string;
}

Make sure to reload or restart Nginx after making changes to the configuration file.
