Another "This transaction is invalid." thread

**shawnz28** · 4 Jan 2008, 07:09 AM

Ok so I am trying to work with the Paypal Express checkout module. I have installed it along with the patch. But am getting the message "This transaction is invalid. Please return to the recipient's website to complete your transaction using their regular checkout flow." when clicking on the paypal link in the cart

Cart 1.3.7 with paypal patch
site - www.saltycritter.com/store

Server info from zen
CURL support enabled
CURL Information libcurl/7.15.3 OpenSSL/0.9.7a zlib/1.2.1.2

Installed the curltest to check that
http://saltycritter.com/curltest.php
not sure if this is the proper SSL link for test?... if so I assume that is the problem.....maybe?
http://saltycritter.com/curltest.php?ssl=1
If so that doesnt seem to work

the ipncheck.php I uploaded gets an error too
http://saltycritter.com/ipncheck.php

I turned logging on as well and here is what I got
www.saltycritter.com/paypal-log.log

thanks as always for any help

Who is your hosting company?

**shawnz28** · 4 Jan 2008, 07:31 AM

www.ultimatehost.com

I found the link about godaddy and some sites needing a proxy for curl so was sending a email to a friend of mine that works at the host to see if I needed that maybe?

Well, the GoDaddy proxy doesn't seem to work any better.

It seems all attempts to do outbound communications over SSL via CURL and fsockopen are failing ... with or without proxy.

**shawnz28** · 4 Jan 2008, 07:35 AM

I would need a proxy though from my host to make it maybe work if that was the problem, correct?

**DrByte** · 4 Jan 2008, 07:36 AM

Possibly, yes. Although it's rare.

You should ask your host why you cannot use CURL or PHP's fsockopen to reach SSL addresses.

I sent him an email with my problems and a link to this thread, as always I appreciate all the help!

Same problem here

Here are the results of the ipncheck.php

Code:

IPNCHECK.PHP - Version 1.0
