: Learn how to update outdated templates

The woocommerce-sendinblue-newsletter-subscription bit in the error message says it all – it’s not a WooCommerce thing ??

Also if the emails work when deactivating their plugin, and stops working when you activate it again, it really is something they’d need to investigate further.

Hi Riaan,

Thanks for your feedback.

I totally agree with your comment and I have provided them with such evidence. However, their technicians claimed its nothing to do with them. I hope they do dig deeper…
