Special server requirements for PayPal Plus?

Yes, please send phpinfo and also send a log from the plugin if you can please.

Where do I find the logs? What is the correct path, woocommerce/logs/paypal_plus.txt

There is no Logs folder int he woocommerce plugin

it would be under /wp-content/uploads/wc-logs/

So in the log we’re seeing this…

“issue”:”Item amount must add up to specified amount subtotal (or total if amount details not specified)”}]

The item totals do seem to be adding up, though, from what I see in the request log, so I’m a little confused myself why we would be getting this particular error.

Is it happening on every single order you attempt or just some item combinations, by chance?

It happens in every single order. In one Shop I even disabled all plugins and the error is still there

With that sort of thing all we can do is submit it to PayPal to see what they can tell us. The error is saying the amounts don’t add up, but based on what I’m seeing they do, so I’m not sure why it would be throwing that error.

I did go ahead and submit a ticket to PayPal MTS with these details, so hopefully we can get some help from them here soon.

OK, lets wait and see what PayPal says.

They are a little confused, too, because they aren’t seeing the problem, and they mentioned that you have successful PayPal Plus transactions coming in to your PayPal account. I guess those must be from the other sites..??

Yes, all three shops have standard PayPal from WooCommerce so there are successful PayPal transactions.

I got some details back from the PayPal MTS rep that should help us find the problem. It’s odd it would only be happening on one of your sites, though.

So you’re just using PayPal Standard, or you are using PayPal Plus on each of them?

All three WC shops have standard PayPal in use and transactions with PayPal are successful.
As soon as I activate and configure PayPal Plus in all three shops I get the error message “Error processing checkout. Please try again.”

Thanks for clarifying. We’ll see if we can reproduce the problem and get it resolved ASAP!

We have been unable to reproduce this error.

We did get some info from PayPal MTS saying that the data was getting POSTed to PayPal twice, and the second time it’s missing the info needed for totals to add up, which is why the error is happening.

Why that would be happening in your case and nobody else’s (no other reports of this) is the question.

Are you using any sort of a caching or CDN service of any kind in WP or on the server directly?

I’m not using a CDN in WP and I will ask my server provider if they have running such a service.
