It looks like either the plugin wasn’t downloaded in it’s entirety or someone has changed or removed some core plugin files. Or, but you should see a message about this in the WordPress admin (“WooCommerce PDF Invoices requires WooCommerce to be installed & activated”), WooCommerce is not recognized and the plugin is not launched (buttons wouldn’t be shown either though). WooCommerce should always be installed in wp-content/plugins/woocommerce. * This function definitely exists in WooCommerce_PDF_Invoices_Export ([code here](https://github.com/wpovernight/woocommerce-pdf-invoices-packing-slips/blob/v1.6.5/includes/class-wcpdf-export.php#L769-L774)), so something else is wrong with the installation somewhere. Let me know what you find! * Ewout * Thread Starter [alexstaff](https://wordpress.org/support/users/alexstaff/) * (@alexstaff) * [8 years, 11 months ago](https://wordpress.org/support/topic/error-404-creating-invoice/#post-9201061) * Thanks for reply Ewout. But what i have to do? I uninstall the plugin and install it again and still having problems generating invoice. * Error 1: – /wp-admin/edit.php?s=&post_status=all&post_type=shop_order&_wpnonce =2000b2e…n=mark_completed&m=0&_customer_user=&paged=1&post%5B%5D=14954&action2 =-1:1 GET [http://dietpremium.es/wp-admin/edit.php?s=&post_status=all&post_type=shop_o…ion=mark_completed&m=0&_customer_user=&paged=1&post%5B%5D=14954&action2=-1](http://dietpremium.es/wp-admin/edit.php?s=&post_status=all&post_type=shop_o…ion=mark_completed&m=0&_customer_user=&paged=1&post%5B%5D=14954&action2=-1) 500 (Internal Server Error) * Failed to load resource: the server responded with a status of edit.php 500 ( Internal Server Error) * Error 2: [http://dietpremium.es/home/dietprem/public_html/wp-content/uploads/2017/06/logo.png](http://dietpremium.es/home/dietprem/public_html/wp-content/uploads/2017/06/logo.png) 404 (Not Found) * – Failed to load resource: the server responded with a status of logo.jpeg 404( Not Found) * Thanks for the help! * Thread Starter [alexstaff](https://wordpress.org/support/users/alexstaff/) * (@alexstaff) * [8 years, 11 months ago](https://wordpress.org/support/topic/error-404-creating-invoice/#post-9201192) * I just saw that both error doesn’t happen if i disable the “Invoice Date”, maybe this information helps you to know what happen. * Thanks. * Plugin Contributor [Ewout](https://wordpress.org/support/users/pomegranate/) * (@pomegranate) * [8 years, 11 months ago](https://wordpress.org/support/topic/error-404-creating-invoice/#post-9201731) * Hi Alex, The 500 error is probably due to the error you posted in the original thread. Turning off Invoice Date solves the issue because it doesn’t look for that function anymore. * I’m not sure where the 404 comes from – is that with the HTML output? * Did you create a custom template? If so, please post it on [https://gist.github.com/](https://gist.github.com/) or [https://pastebin.com/](https://pastebin.com/) * Which version of the plugin are you using? Did you make any modifications to the plugin files (besides the templates)? * Thread Starter [alexstaff](https://wordpress.org/support/users/alexstaff/) * (@alexstaff) * [8 years, 11 months ago](https://wordpress.org/support/topic/error-404-creating-invoice/#post-9201991) * Hello ewout, * I’m using Modern template. I’m using 1.6.5 version. * I need to put the Invoice Date.
