Pay Pal Error!! (CURL is slow, causing error)

Whenever I want to choose pay woth pal pal, it gives me this error message > This transaction is invalid. Please return to the recipient's website to complete your transaction using their regular checkout flow.
I don't know what it means or how to fix it. I checked the paypal settings and everything should be working fine but i still get the error pleas help me.

Are you trying to use your own account to test the system?

No, im not. the paypal IPn works but whenever i choose paypal express is when i get the error

1. Ensure you've installed the latest PayPal patch for v1.3.7:

2. Turn on debug logging:

3. Do a test transaction and post a copy of the various debug logs generated.

Which patch do i install for my problem there are so many.

Ignore the last post i saw that they were cumilitive to the ones above it. How do you install it , do you replace the files in the patch with the ones on the server

ok this is what the log had in it

Is this supposed to tell me whats wrong? I don't know if it helps but i think i started to get the ptoblem after i reset my username and password, since I lost it i had to chage it to admin in PHPmyAdmin, don't know if it would mess anything up.

For some reason your connection to PayPal's server is failing.
Either CURL is not working or CURL is not allowed to talk externally on port 80.

What does that mean?

Ask your host whether there are any prohibitions in place which would prevent you from talking to paypal on port 80 via CURL.

DrByte.

Can you explain my error for me as I am getting the same errors....

This suggests that your webserver CURL engine is disconnecting before data can be received.
I don't know the exact causes of this - it largely depends on your webserver setup.
Perhaps report the CURL error to your host and ask for them to determine whether CURL is truly functioning properly or not.

On most hosts it just works as-is. If your host has some unique firewall configuration or other technical setup, you may have problems. You'll need to get them to help figure it out.

Error #18 corresponds to: > CURLE_PARTIAL_FILE (18):

A file transfer was shorter or larger than expected. This happens when the server first reports an expected transfer size, and then delivers data that doesn't match the previously given size.

Googling the CURL error brings this post, which suggests the server has a problem:
http://curl.haxx.se/mail/archive-2002-01/0152.html

Another one suggests that perhaps there's a very slow communication link between your server and the PayPal one:

Thanks for looking.

The Paypal IPN worked perfectly, but not the Express.

Thanks anyway.

I'm having the same error, and I'm totally pulling my hair out over it!
I've contacted my host (Dreamhost) to see if the Curl port is cool....:shocking: :censored: :frusty:
Other than that, please, for the love of all that is Holy, someone help me out here..

If you want to see this in action, go to MIsight.com and try using the PayPal Express...

Paypal has blamed ZenCart....Which I fail to believe!

THANKS AHEAD OF TIME!
