[Support request] PHP error regarding WooCommerce

Hey there.
My PHP error log shows some errors but I’m not sure if it is a Generatepress thing or a plugin thing that’s working together with WooCommerce.
So to make sure it’s not GP (and thus assuring other users) I’ll ask if this error has anything to do with GP:

add_to_cart_fragments is deprecated since version 3.0.0! Use woocommerce_add_to_cart_fragments instead.

and

post was called incorrectly. Product features shouldn’t be called directly. Backtrace: require(‘wp-blog-header.php’), require_once(‘wp-includes/template-loader.php’), do_action(‘template_redirect’), WP_Hook->do_action, WP_Hook->apply_filters, WC_AJAX::do_wc_ajax, do_action(‘wc_ajax_get_refreshed_fragments’), WP_Hook->do_action, WP_Hook->apply_filters, WC_AJAX::get_refreshed_fragments, apply_filters(‘woocommerce_add_to_cart_fragments’), WP_Hook->apply_filters, WC_Deprecated_Hooks->maybe_handle_deprecated_hook, WC_Deprecated_Filter_Hooks->handle_deprecated_hook, WC_Deprecated_Filter_Hooks->trigger_hook, apply_filters_ref_array, WP_Hook->apply_filters, tho_filter_product_title, WC_Abstract_Legacy_Product->__get, wc_doing_it_wrong. This message was added in version 3.0

Now does any of this ring a bell? I assume it is another plugin, but just to make sure it has nothing to do with GP.

Best regards,
