 * Dear Dev hello,
   I will try to clearly describe and structure my problem(s).1)
   I recently got an issue, for no reason, the mails do not send the PDF anymore.
   2) I manualy tried to send a regular mail from an invoice, and wordpress whos
   a fatal error.”There has been a critical error on this website. Please check 
   your site admin email inbox for instructions.”3) I then manualy tried to send
   a mail trough the plugin (the small mail icon on the order edit). Same problem,
   red shield with “an unexpected error occur, please try again”.4) I disable plugins
   1 by 1 and found it the problem comes from “woo-pdf-invoice-builder”.5) After
   disabling it, I’m able to resend the notification mails for the invoices.6) I
   just update plugin to last version but still the same issue.7) I also figured
   out I cannot edit the template. Well I actualy can edit but I cannot save it.
   It keep running fool forever.Any idea? Any solution? Nothing seems to had chanced
   since then and few days ago it worked just fine.Many thanks in advance for your
   help,With regards,

 * Hi [@pingwinbe](https://wordpress.org/support/users/pingwinbe/):
 * I’m afraid you are using a PDF invoices plugin from a different company: `woo-
   pdf-invoice-builder` seems to be the slug of this plugin: [https://wordpress.org/plugins/woo-pdf-invoice-builder/](https://wordpress.org/plugins/woo-pdf-invoice-builder/)
 * Just to clarify, our plugin is [PDF Invoices & Packing Slips for WooCommerce](https://wordpress.org/plugins/woocommerce-pdf-invoices-packing-slips/)
   by **WP Overnight**. If you have any issues with them, you might give our plugin
   a try 😉

 * Search no more,
   It was related to server’s rights. All solved by now.Thank you!
