Accessing Uploaded Attachments and Images Return HTTP 302 with Location /403

Reproduce el problema con el binario 1.4.5 usando answer init -C ./answer-data/ y answer run -C ./answer-data/; después inspecciona las URL de carga, las redirecciones, confi.yaml y los archivos bajo answer-data/uploads/. Rastrea por qué las solicitudes de imágenes y archivos adjuntos se redirigen a /403; se considera terminado cuando las imágenes se muestran y los archivos adjuntos se descargan correctamente.

Describe the bug

Add images and attachment to a post successfully, no error shows up, and then reopen the post, but image isn't displayed and attachement can't be downloaded.

I inspect the network activities. Refreshing the post with the image sends HTTP GET, but receives HTTP 302 response with location /403.

Clicking the attachment sends the HTTP GET, but receives HTTP 302 response with location /403.

Steps to reproduce the behavior:

1. Unpack binary distribution from github, to directory ~/apache-answer-1.4.5-bin-linux-amd64, where there is the executable.
