 * Hello, I recently discovered two legitimate costumers blocked as “SPAM”. I checked
   the above recommendation “Use Anti-Spam by CleanTalk JavaScript library” set 
   to “ON” which it already was.
 * Any other idea why this is happening?

 * 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://wordpress.org/plugins/woocommerce-pdf-invoices-packing-slips/](https://wordpress.org/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/](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!
