I am using Authorize.net in my application(its in OSCOMMERCE) , When the user making payment its returning empty response. I debugged and find that it returning this error:
Protocol https not supported or disabled in libcurl
I am sending a prober url starts with https there is no space in that https://secure.authorize.net/gateway/transact.dll
My application in shared hosting server. My doubt is this is server side problem or Programming problem ?
I had this problem and it was because of space in url:
' https://www.google.com/recaptcha/api/siteverify'
as you see there is a space before https
