I have been getting:

413 Request Entity Too Large
The requested resource
/XXXXXXXXX/apsona_svc.php
does not allow request data with GET requests, or the amount of data provided in the request exceeds the capacity limit.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

Zen Cart 1.5.4 PHP Version 5.4.40 --

Was working great a couple of weeks ago and we made no changes to the server. Anybody else seen this?

Uploads just fine - just does not download
