Hi @mkbarraco,
In the email, you suggest me to check about Woocommerce Block plugin. Wich is missing in my client’ website.
This error comes from the core block functions, not the added WooCommerce Blocks plugin, which is why the previous reply was edited. ??
When you tested for conflicts, did the same thing happen with only WooCommerce enabled and no other plugins?
What steps do you take to get the error? Is it while browsing the site, editing a page, something else?
Could you also please share a copy of your site’s System Status? You can find it via WooCommerce > Status. Select “Get system report” and then “Copy for support”.? Once you’ve done that, paste it here in your response.
Thanks!
