GP Theme causing errors with Woocommerce

Then, when enabling Woocommerce, I get the following errors:

Notice: product_type was called incorrectly. Product properties should not be accessed directly. Backtrace: require('wp-blog-header.php'), require_once('wp-includes/template-loader.php'), include('/plugins/woocommerce/templates/single-product.php'), wc_get_template_part, load_template, require('/plugins/woocommerce/templates/content-single-product.php'), do_action('woocommerce_single_product_summary'), WP_Hook->do_action, WP_Hook->apply_filters, woocommerce_template_single_price, wc_get_template, include('/plugins/woocommerce/templates/single-product/price.php'), WC_Product_Variable->get_price_html, apply_filters('woocommerce_get_price_html'), WP_Hook->apply_filters, lw_hide_variation_price, WC_Abstract_Legacy_Product->__get, wc_doing_it_wrong Please see Debugging in WordPress for more information.

Again, these errors disappear with Twenty Nineteen

Hi there,

are you using a child theme with any custom functions or any code added via the Hook Element?

I can confirm that there are no custom functions/elements, also no code added via the hook element.

I've also deleted the GeneratePress theme, re-uploaded from scratch to make sure that the files are original.

I've found a workaround (but haven't found the cause):

"That notice is appearing because there are some items in the Menu that are leading to WooCommerce, which is not installed. We suggest that you delete Shop pages from the Menu. You can install WooCommerce if you plan to use it in the future.

Please navigate to Appearance> Menus and delete the invalid links related to the notice (in all menus)."

I do have WooCommerce installed, but I did a cleanup of my defunct menus and the problem has disappeared.

Bizarre.

Glad you found the solution - it sounds like a bug in WooCommerce itself.

The reason it went away when you switched themes is the menus are theme-specific and are reset on theme change.

Thanks for sharing the fix! :)
