Notification Required for "Information" Sidebox Link

v4.0.0 of PPL makes use of a notification introduced via this Zen Cart v2.0.1 PR. That notification is also included in v3.7.0 and later of the ZCA Bootstrap Template.

If your store is running on Zen Cart 1.5.8a or 2.0.0 or using a version of the ZCA Bootstrap Template less than 3.7.0, you will need to hand-edit your active template's version of /includes/modules/sideboxes{/active-template}/information.php. In that file, you'll see a code fragment similar to

if (SHOW_NEWSLETTER_UNSUBSCRIBE_LINK == 'true') {
    $information[] = '<a href="' . zen_href_link(FILENAME_UNSUBSCRIBE) . '">' . BOX_INFORMATION_UNSUBSCRIBE . '</a>';
}

Add the required notification to the file:

if (SHOW_NEWSLETTER_UNSUBSCRIBE_LINK == 'true') {
    $information[] = '<a href="' . zen_href_link(FILENAME_UNSUBSCRIBE) . '">' . BOX_INFORMATION_UNSUBSCRIBE . '</a>';
}

$zco_notifier->notify('NOTIFY_INFORMATION_SIDEBOX_ADDITIONS', [], $information);

Note: Without the above notification, the "Information" sidebox link to the Printable Price List page (pricelist) will not appear!
