[Answer]-Big file upload failure using django-ajax-uploader

What frontend server do you use (Apache, nginx)? You need to check it settings.

EDIT: If you’re using nginx you need something like this:

server {
        listen   80;
        server_name example.com;

        client_max_body_size    64m;
}

For apache something like so:

upload_max_filesize = 64M
post_max_size = 64M

You could check that the problem is with the frontend server by:

1. run ./manage.py runserver 0.0.0.0:8000 on production server – this runs ‘developer’ server on port 8000 and allows to connect from your computer
2. go to yourdoamin.com:8000 and try to upload a large file. It should work fine.
