Hello Leslie,
Regarding update messages for woocommerce template files, you can simply ignore the message unless it creates any issues while we’ll have a next update soon.
The message i.e; WooCommerce Pay Per Post by Matt Pramschufer – 1.4.9 – Not tested with the active version of WooCommerce is associated to the particular plugin you’ve been using so make sure you check if the plugin is preferrable or not.
Best Regards,
Bidur
