Blank Screen

Hi there,

I have the same issue.

A few days ago we’ve updated WooCommerce (Version 10.3.3) and WooCommerce Pre-Orders (Version 2.3.1). Unfortuately the Product Sales Report (now Ninjalytics) doesn’t work anymore. Deactivating WooCommerce Pre-Orders does the trick, but unfortunately I need it.

I’ve already contacted the WooCommerce Support (I guess a KI) and they suggested to get in contact with you.

Thanks!

Hi,

just to clarify  we don’t have a blank screen. The reports load normally, but no sales data are shown.

Environment:

WordPress 6.8.3
WooCommerce 10.3.3
Ninjalytics Free (formerly Product Sales Report) 2.0.3
WooCommerce Pre-Orders 2.3.1

When Pre-Orders is active, Ninjalytics shows no results. As soon as we disable Pre-Orders, all reports work normally again with the same filters.

We analyzed the SQL query used by Ninjalytics and found the following structure:

SELECT 
  GROUP_CONCAT(DISTINCT order_items.order_item_name) AS field0,
  SUM(order_item_meta__line_subtotal.meta_value) AS field1,
  SUM(order_item_meta__line_total.meta_value) AS field2,
  SUM(order_item_meta__line_tax.meta_value) AS field3,
  order_item_meta__product_id.meta_value AS field4,
  SUM(order_item_meta__qty.meta_value) AS field5
FROM wp_posts AS posts
LEFT JOIN wp_woocommerce_order_items AS order_items
  ON (posts.id = order_items.order_id)
  AND (order_items.order_item_type = 'line_item')
LEFT JOIN wp_woocommerce_order_itemmeta AS order_item_meta__line_subtotal
  ON (order_items.order_item_id = order_item_meta__line_subtotal.order_item_id)
  AND (order_item_meta__line_subtotal.meta_key = '_line_subtotal')
LEFT JOIN wp_woocommerce_order_itemmeta AS order_item_meta__line_total
  ON (order_items.order_item_id = order_item_meta__line_total.order_item_id)
  AND (order_item_meta__line_total.meta_key = '_line_total')
LEFT JOIN wp_woocommerce_order_itemmeta AS order_item_meta__line_tax
  ON (order_items.order_item_id = order_item_meta__line_tax.order_item_id)
  AND (order_item_meta__line_tax.meta_key = '_line_tax')
LEFT JOIN wp_woocommerce_order_itemmeta AS order_item_meta__product_id
  ON (order_items.order_item_id = order_item_meta__product_id.order_item_id)
  AND (order_item_meta__product_id.meta_key = '_product_id')
LEFT JOIN wp_woocommerce_order_itemmeta AS order_item_meta__qty
  ON (order_items.order_item_id = order_item_meta__qty.order_item_id)
  AND (order_item_meta__qty.meta_key = '_qty')
WHERE
  posts.post_type IN ('shop_order')
  AND posts.post_status IN ('wc-pre-ordered')
  AND posts.post_date_gmt >= '2014-12-31 23:00:00'
  AND posts.post_date_gmt <= '2025-12-31 22:59:59'
  AND posts.post_status IN ('wc-processing','wc-on-hold','wc-completed')
GROUP BY field4;

As you can see, there are two conflicting post_status conditions. The query requires orders to be both 'wc-pre-ordered' and 'wc-processing'/'wc-completed' etc. at the same time, which is logically impossible — this always returns an empty result set.

This behavior only occurs when the WooCommerce Pre-Orders plugin is active. Once it’s deactivated, the same report runs correctly.

There are no errors in the browser console or in debug.log.

Thanks for looking into this — it seems to be a direct conflict between Ninjalytics and Pre-Orders.

Thank you very much for the reply.

Unfortunately, the fix you are suggestiong is only possible in the pro version, which we don’t have.

Looks like I have to live with my “fix”: deaktivating the pre-order function – for a short time – to run a report.
