If the page is *blank* it usually means that the file has been modified and has probably had a blank line added to the end of it.
However, you are not getting a blank page, so this probably isn't the cause of your problem.
Being unable to get a VALID quote can be caused by MANY things. Parcel too heavy. Parcel too large, no suitable shipping methods allowed, unable to contact the servers, and so forth.
Yes, the Curl problem *could* be related.
Whether or not the AustPost module specifically needs cURL depends on your server.
Some servers only support cURL file access, others only support the FILE method of access, and yet other servers support both.
The AustPost module will support either method, but needless to say, is it pointless having the AP module using one method if your server only supports the other.
Does that help?
