    Default Intermitted order generation issues

    https://www.tolivealie.com/store
    v1.5.7
    Only payment plugins
    PHP Version 7.3.33 (Zend: 3.3.33)

    Please move to payments section (or elsewhere) if needed. I'm having random issues, maybe every 20 orders, where I get Paypal payment but no order information at all. I can't seem to triangulate if they are closing their browser right when Paypal says complete or what exactly is happening here. The person may have existing orders when I look at the customer, may have a login count, but I have zero new order - no email, nothing in Orders, and the stock does not decrement.

    This exact same thing is happening on a friends store. I tried his store and got no order through because he did not have SSL set up and my browser forces HTTPS but my site has a valid SSL certificate so that can't be the issue - but I'm mainly starting to troubleshoot my store to help him and obviously it's a big issue for me as well I have just been too busy to spend the time to figure this out.

    This problem has been happening for a fairly long time, probably a few years, but is much more an issue now. My store was originally installed in 2009 on v1.3.8 and I have kept up with upgrades.

    In looking, Paypal is not listed in Payment modules but I do see a Paypal IPN under customers. I do not see the order I got today that didn't come through but payment come through on this page. I guess the Paypal module changed where its located now from where I'm used to seeing it. Either that or one of my upgrades makes me not see it under payments.

    Hopefully that is enough information to help me start to diagnose this. It is super strange to me that most orders come through fine, it's just certain ones don't.

    You're seeing a 'partial whitepage', indicating that there's a PHP error in one of the payment modules. You can view the logs by (if you haven't already) enabling the "Display Logs" built-in plugin.

    Also, once you get this fixed you will want to be sure you're using PayPal Express rather than PayPal Standard. The situation you are describing is one of the issues that can occur with PayPal Standard.

    I'm on my phone and have been busy but I installed and enabled logs and it showed me a log to click on and I got a HTTP 500 reply.

    Try to FTP to your site and pull down the logs to your computer. They're under the /logs folder.

    Those are just warnings; there's another one out there.
    But to fix the issue with MODULE_PAYMENT_PAYPALDP_MERCHANT_COUNTRY do a Remove and Re-Install of PayPal. Note your settings before doing this.

    How do I remove this when I can't see these modules?
