PDFs Not being displayed because of errors at top.

Deprecated: WC_Order_Item_Product::offsetSet is deprecated since version 4.4.0 with no alternative available. in /home/natu9588/public_html/wp-includes/functions.php on line 4783

Warning: Cannot modify header information – headers already sent by (output started at /home/natu9588/public_html/wp-includes/functions.php:4783) in /home/natu9588/public_html/wp-content/plugins/booster-plus-for-woocommerce/includes/classes/class-wcj-pdf-invoice.php on line 237

Wordpress version: 5.5.1
WooCommerce version: 4.5.2

This code is at the top of each pdf “invoice” and “packing slip” generated and viewed in google chrome. Also if downloaded as zip it will not open. Below this code seems to be what a pdf would look like rendered in html. ex: (%PDF-1.7 %���� 7 0 obj) We have another site with a lot of the same plugins and it works fine. But we have gone through and deactivated most plugins to find a culprit without success.
If anyone has any ideas or thinks they could help but needs more info please let us know.

Hi Omar,

Please set the following in the wp-config.php file and see if the issue is resolved. Thanks

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

Thanks!
