Hello all,
As developer of WooCommerce DYMO Print we’ve get into this issue.
As soon as your plugin “Print Invoice & Delivery Notes for WooCommerce” is installed the BULK printing options are changed and the BULK printing options of our plugin WooCommerce DYMO Print (PRO version) are not working anymore.
We’ve get into the code and found that in /wp-content/plugins/woocommerce-delivery-notes/includes/class-wcdn-writepanel.php
filter / function my_bulk_action_handler the returned redirect_to url is changed by your plugin EVEN if this is not necessary.
We advise to check if the correct args are send.
For example to add a if statement like below on line 140:
if(!in_array($_REQUEST['action'],array('wcdn_print_invoice','wcdn_print_delivery-note','wcdn_print_receipt'))) return $redirect_to;
Hopefully this will help you solving this issue.
Best regards,
Bart
