www error -> http not supported or disabled in libcurl -

Would anyone have any insight as to what this error means or why it's happening?

IEnumerator GetModels(int year)
{

string url = "http://xxx.170.58.57/ListModels.php?year=2013";

WWW www = new WWW (url);

while (!www.isDone){
yield return null;
}

print (www.bytesDownloaded);

print (www.error);

print (www.text);

}

Thanks!

 

I cant see any problem in url. Probable you have not clean url string, I had same error when work with UTF-8 string it seems well, but had invisible UTF-8 chars. Try to convert file with your source code to simple windows ASCII format.
