Causing “Internal Error” message on checkout

    Hello,
    It appears this plugin is causing a “Internal Error” message to be displayed after an order is submitted on checkout. WordPress version “4.9.2” and WooCommerce version “3.3.0”. Checked our logs and got “2018-01-30T12:42:50+00:00 CRITICAL Call to a member function get_pdf() on null”. I deactivated the plugin, all works well. This error is causing customers to do the order again thinking the first order did not go through resulting in duplicate orders. This error is gone since I deactivated the plugin. Any idea on what is happening?

    I use this plugin to auto print packing slips with the WooCommerce Print Orders / Google Cloud print
    Thank you

    Hi! I’m sorry to hear that. To determine what causes this, I need a bit more information. First and foremost, which version of “WooCommerce Print Orders” are you using? (latest is 2.7.7).
    What’s the full error after the “function get_pdf() on null” bit? This helps in determining where this is triggered exactly. If you have a stack trace, even better.
    Which version of PDF Invoices are you using and did you recently update from a 1.X version (or have you been using 2.X for some time already?).

    Let me know and I’ll do my best to help!

    Hello,
    Thank you for your reply. We have the WooCommerce PDF Invoices & Packing Slips version 2.1.4. This shows as the latest version here: https://ww.wp.xz.cn/plugins/woocommerce-pdf-invoices-packing-slips/ so we were unaware there was a newer version. How do we get the latest version? Also, the version of “WooCommerce Print Orders” by: https://www.simbahosting.co.uk/s3/product/woocommerce-automatic-order-printing/ is “Version 2.5.1”. Everything worked up until we updated WordPress to the latest 4.9.2 and WooCommerce to 3.3.0.
    The last three errors we got were:
    2018-01-30T12:12:28+00:00 CRITICAL Call to a member function get_pdf() on null

    2018-01-30T12:14:55+00:00 CRITICAL Call to a member function get_pdf() on null

    2018-01-30T12:42:50+00:00 CRITICAL Call to a member function get_pdf() on null
    we then deactivated the WooCommerce PDF Invoices & Packing Slips plugin and the “Internal Error” message is gone and all orders are being processed as expected without issue.

    Thank you!

    Hi!
    I think you found the issue: WooCommerce Print Orders is heavily outdated at 2.5.1, as mentioned in my post 2.7.7 is the latest (indeed you’re already using the latest of PDF invoices at 2.1.4).
    2.5.1 is not compatible with WooCommerce 3.X (required Print Orders 2.5.5 minimum) and also not compatible with PDF invoices 2.X (requires 2.5.17 minimum)

    I recommend checking if your license for print orders is still valid and contact Simba Hosting support about getting the latest version.
