Finally I wrote a small clumsy plugin that solves my problem, maybe it’s useful for somebody else. (I’m not a developer so use carefully).

The options stored in site 1 (defined in variable $mainsite) overwrites all other sites options. I could add a network setting page to manage the options or simply set the main site, but for me is enough in that way. Thank you @kittmedia for your help!

Thank you very much, I made a fresh install and I only installed WooCommerce and PDF Invoices & Packing Slips and then I tried with php 8.2.12 (not supported by WooCommerce) and the error persists, with php 8.0.30 the error it’s not showed.

I know it’s not a critical issue but I thought that you probably want to know for future releases (especially if is not your fault)

Thank you for your attention
