PHP Warning: Trying to access array offset on value of type bool

I’m sorry, but in our test we cannot reproduce this error.
Can you specify on what occasion it happens?

After following all your suggestions for upgrading to v0.7.6, saving all the settings, and replacing the receipt.php file. On the PDF Invoices & Packing Slips for WooCommerce admin page > Documents > Invoice > Previewing an EU based order. The following warning is stated. ( the warning does not show for non-EU orders )

PHP message: PHP Warning: Undefined array key “txtVatExemptUE” in /var/www/html/wp-content/plugins/woocommerce-pdf-invoices-italian-add-on/includes/class-wcpdf-integration3.php on line 448″

2024/11/13 13:16:15 [error] 160#160: *422 FastCGI sent in stderr: “PHP message: PHP Warning: Undefined array key “txtVatExemptUE” in /var/www/html/wp-content/plugins/woocommerce-pdf-invoices-italian-add-on/includes/class-wcpdf-integration3.php on line 448″ while reading response header from upstream , request: “POST /wp-admin/admin-ajax.php HTTP/1.1”, upstream: “fastcgi://unix:/var/run/php/php-fpm.sock:”, page=wpo_wcpdf_options_page&tab=documents&section=invoice”

If I then go to the order page and and use the “PDF Receipt” button a similar warning is created.

Settings: VAT/Tax Code always required = depends on billing country and user selection, (1) Hide the Italian Add-on fields if billing country is outside UE? = not required, If customer does not choose between invoice or receipt = Don’t issue any invoice or receipt, VAT/Tax Code field position = after Email field, VAT/Tax Code field width = Wide, Adds the fields for Electronic Invoicing = No

Founded. Thanks for the advice.

We have published a new update.

Thanks, I confirm no repeat of warning/error after update.
