Odd issue with PDF invoicing

[Jan]

Hi team,

We have an issue with PDF Invoicing where on one order the PDF that generated had no data and couldn’t be opened. Deleting the invoice and regenerating did not fix the issue. We have over 100 other orders that haven’t been a problem. The issue was first detected when the client when to bulk export the PDF invoices from orders, and the broken PDF caused a critical error:

Aside from the usual culprits (plugin conflicts, etc), what should I be looking for? Since this site will be generating quite a few orders, I’d like to get ahead of this issue before it becomes a regular problem.

Hello @janetrosehenry,

Thank you for reaching out to us.

PDF invoices cannot be opened properly on some servers due to an error log conflict. So added below code on you wp-config.php. The query plugin also follows this method. that’s why it was working when you activate it.

@ini_set( ‘log_errors’, ‘On’ );
@ini_set( ‘display_errors’, ‘Off’ );
define( ‘WP_DEBUG’, true );
define( ‘WP_DEBUG_LOG’, true );
define( ‘WP_DEBUG_DISPLAY’, false );

I’ve already addressed this here, with no answer. And I’m paying for the license. It just doesn’t work. This is what happens:

🙂 I can’t upload it, your security plugin is blocking me.

It’s quite specific. Can you help?

One more addition – the invoice is sent correctly by email. However, it cannot be downloaded from WooCommerce or FTP – either a fatal error or a corrupted file.

Hi David,

In staging the invoice generates successfully, even without adding that code to the wp-config.php file. When I add that code to the wp-config.php file on the live site, it still doesn’t work on that one order.
