Package Archive:

This file should be either the .json template file, or a .zip pack archive containing archive.(zip|tar.gz) and import.json within.

This server is currently configured with the following limits: upload_max_filesize={{ ini_get('upload_max_filesize') }} and post_max_size={{ ini_get('post_max_size') }}. If your file is larger than either of those values this request will fail.
