I'm getting this error when I try to update my store from within WP:
Cannot download store data (curl_error)
download: using curl (http://factory3.datafeedr.com/feeder...afde7b7033ba02
ERROR: curl_error (Empty reply from server) error:704,call.updater.download_shop_update:3086,d o_remote_update:3073,shop_update:2405,cmd_quick_up date:2356
remote_update: FAIL: download error
shop_update: 1295755501-1295755502 (err_download:curl_error)
It's been working fine for me for the last couple of days, then suddenly this error. And I'm all updated version-wise.
