I dunno if you know about this but i have asked woocommerce who said its nothing to do with a core woocomerce file.

On wp engine in the error logs i get loads fo messages

[client 86.136.15.84:37580] The The "add_to_cart_fragments" hook uses
out of date data structures and function is deprecated since version
3.0.7. Replace with woocommerce_add_to_cart_fragments., referer:

They said

That
error message isn't in a WooCommerce core file because our platform no
longer uses that particular hook, it's deprecated. It's coming from one
of the other third-party plugins on the site.

As Danny asked previously, What is the behavior if you temporarily switch to the default WordPress theme ( Twenty Sixteen )?

Please test also with all non-Woo plugins disabled to rule out a conflict.

I have tried the theme and made no difference.

Do you have any ideas where the file could be that needs updating or any solutions?

Thanks
