 * hi there,
    Long term user of this excellent plugin & the Pro version. I’m getting
   the PHP error on the page above from Rank Math & also a problem with the Gift
   Tokens creating using the Woocommerce Ultimate Giftcard plugin – these both disappear
   when I deactivate WooCommerce PDF Invoices & Packing Slips
 * Happy to provide further details.
    Thx Niall

 * Hello Niall,
    Is it possible that you have simply enabled “Debug output” on the
   Status tab of the PDF invoice settings? This would display errors from other 
   plugins too.

 * Hi Ewout,
    That got rid of the error from Rank Math alright – but it is still
   knocking out the Gift Token plugin, I’ll try & get some error messages for you,
   Thanks for getting back, Niall

 * That’d be quite helpful if you could get us those error messages we can see what
   exactly causes the plugin conflict and hopefully provide a fix.
