WooCommerce as MU-plugin | WordPress.org

Hi @areklam,

This subject has been discussed here. In brief, we have added a filter that you can use to force the WooCommerce installation check, returning true:

/**
 * PDF Invoices & Packing Slips for WooCommerce:
 * Forces the value returned by the WooCommerce check as true.
 */
add_filter( 'wpo_wcpdf_is_woocommerce_activated', '__return_true' );

If you haven’t worked with code snippets (actions/filters) or functions.php before, read this guide: How to use filters
