Hello,

I would appreciate if anyone can explain the reason for these error codes.

Many thanks

Um, in your post title you said you're using Zen Cart v155 .... is that really true?

The SSL errors you mention STRONGLY indicate that you're using an old version of Zen Cart with old PayPal code, and/or your hosting server is not compatible with PayPal's infrastructure changes that they've been announcing and upgrading over the past 2 years.

One way to find your ZC version is through the version link at the top right of your admin window. Another is through inspection of the file: includes/version.php about half way down the page. Please provide that information to support DrByte's statement.

Apologies. 1.5.1.

Is there a solution to these error codes?

Thanks.

Thanks.

Yes. Patch today to get your site working again. And later this week upgrade to a modern version of Zen Cart.

We are using 1.5.1 with both patches applied already yet still get these errors.

[DrByte]

Then it's likely that your server itself needs the required updates that PayPal has been posting about for 2 years.
... so your hosting company will need to modernize the server's internal configuration.

Spoken to my host:

As I checked,SSL/TLS Protocols is set to All -SSLv2 -SSLv3 -TLSv1 and it is compatible with the SHA-256 algorithm

Current apache version on the server is 2.2.29

Openssl version is 1.0.1e-fips.

SSL Rating is A-

[CURL_ERRORS] => (56) SSL read: error:00000000:lib(0):func(0):reason(0), errno 104

Error 104 means "Connection reset by peer", which is what happens when PayPal sees you connecting over a protocol that they've disabled.

106 Host not available - Host not available

Could be similar to the above, or could be a problem in your server which is making it unable to connect to PayPal (ie: tried to connect, but got a response back saying "not available" but didn't say why. I don't recall ever encountering this one myself, but it's pretty self explanatory)

ALERT: PayPal Direct Payment Error
Customer arrived on the order process page without attempting authentication lookup.

That's probably a byproduct of encountering one of the above errors

Zen Cart message: We were not able to process your order. Please select an alternate payment method, or contact the store owner for assistance. ( 1000 [Generic processor error: 10001-Internal Error]) Generic processor error: 10001-Internal Error -

The 10001 error is caused for many reasons. Sometimes it's because PayPal is doing maintenance (they usually email everyone when that's scheduled). Sometimes it's because you've put wrong credentials into your PayPal module in your store admin.

Field format error: 10444-The transaction currency specified must be the same as previously specified. - 7

At the risk of stating the obvious, that means a transaction started with one currency, but it got changed between the first initiation and the final completion/charging of the account. That shouldn't happen, but if you're truly encountering all these combinations of errors above on a daily basis, then there's something strange going on for sure.


It would be much easier to troubleshoot if you were using a modern version of Zen Cart.
