Hi there.
I am using your plugin for severl years and I am very satisfied.
However I tried to access parameters of the plugin and got a fatal error with the following message.
Fatal error: Uncaught Error: Cannot access private property WPO_WCPDF_Templates::$updater in /htdocs/wp-content/plugins/woocommerce-pdf-invoices-packing-slips/includes/settings/class-wcpdf-settings-upgrade.php:178 Stack trace: #0 /htdocs/wp-content/plugins/woocommerce-pdf-invoices-packing-slips/includes/settings/class-wcpdf-settings-upgrade.php(326): WPO\WC\PDF_Invoices\Settings\Settings_Upgrade->get_extension_license_infos() #1 /htdocs/wp-content/plugins/woocommerce-pdf-invoices-packing-slips/includes/class-wcpdf-settings.php(209): WPO\WC\PDF_Invoices\Settings\Settings_Upgrade->bundle_is_active() #2 /htdocs/wp-includes/class-wp-hook.php(324): WPO\WC\PDF_Invoices\Settings->settings_page(”) #3 /htdocs/wp-includes/class-wp-hook.php(348): WP_Hook->apply_filters(”, Array) #4 /htdocs/wp-includes/plugin.php(517): WP_Hook->do_action(Array) #5 /htdocs/wp-admin/admin.php(259): do_action(‘woocommerce_pag…’) #6 {main} thrown in /htdocs/wp-content/plugins/woocommerce-pdf-invoices-packing-slips/includes/settings/class-wcpdf-settings-upgrade.php on line 178
