我有一个文件名为Chu Thái.jpg. 上传到媒体库时，hosting中的文件名已重命名为Chu-Thái.jpg，但图片的路径与文件名不同：http://bem.vn/httq/wp-content/uploads/sites/2/2013/10/Chu-Thái.jpg

因此，当将 url 复制到浏览器中时，它会说在此服务器上找不到该文件。

The requested URL /wp-head/wp-content/uploads/sites/2/2013/10/Chu-Thái-150x150.jpg was not found on this server.

我想知道 Wordpress 或我的托管问题是如何引起的？

问题是您不应该上传包含特殊字符的文件。我在我的插件中使用的是 filter sanitize_file_name。

我最终从这个插件中提取并调整了3个函数，以便对上传的文件名进行全面清理，以免出现这种错误：

add_filter( 'sanitize_file_name', 't5_sanitize_filename', 10 );

/**

    return $filename;
