 * Hi!
 * I’ve tested all my plugins with this PHP linter:
    [https://wordpress.org/plugins/php-compatibility-checker/](https://wordpress.org/plugins/php-compatibility-checker/)
 * Unfortunately I found a problem with your plugin:
 * FILE: /srv/www/vhosts/nessuna.ch/httpdocs/nessuna/wp-content/plugins/woocommerce-
   pdf-invoices-packing-slips/lib/dompdf/include/page_cache.cls.php
    —————————————————————————————————————————————————
   FOUND 0 ERRORS AND 1 WARNING AFFECTING 1 LINE —————————————————————————————————————————————————
   40 | WARNING | Method name “Page_Cache::__query” is discouraged; PHP has reserved
   all method names with a double underscore prefix for future use —————————————————————————————————————————————————
 * Would be great if you can fix this!
 * Regards,
    Demian
