设置ALLOW_UNFILTERED_UPLOADS后，Wordpress文件下载404

Question

我在nginx上使用WordPress 5.1，并且通过在 ncalls tottime percall cumtime percall filename:lineno(function) 1000 1.332 0.001 1.672 0.002 <input>:11(assemble_substrings) 3654000 0.227 0.000 0.227 0.000 {method 'append' of 'list' objects} 525000 0.112 0.000 0.112 0.000 {built-in method builtins.min} 1000 0.000 0.000 0.000 0.000 {built-in method builtins.len} 1 0.000 0.000 0.000 0.000 {method 'disable' of '_lsprof.Profiler' objects} 这一行wp-config.php中进行设置，允许上传所有文件类型。现在，我可以上传任何内容，但仍然可以下载“允许”的文件，例如图像，但是不能下载其他自定义文件。我收到404错误，但是从nginx日志中，我尝试通过链接访问的文件实际上位于该确切路径下。

链接示例：define( 'ALLOW_UNFILTERED_UPLOADS', true ); 我从Wordpress的媒体管理器中获得了此链接。
