Hi Adam,

good news — the issue has been resolved.

The cause was the Site Kit setting that excluded all logged-in users from Analytics tracking.

During the WooCommerce checkout flow, the customer was being treated as logged in on the order-received page. Because of that, Site Kit was adding:

window["ga-disable-G-W842EZ2B1Z"] = true;

on the order-received page, which prevented the GA4 purchase event from being recorded even though the purchase event itself was correctly present in the dataLayer.

We confirmed that:

• purchase was present in the dataLayer
• gtagEvent was available
• eventsToTrack contained add_to_cart and purchase
• hasPurchase was true
• the Google tag and Google Ads tag were loaded
• the WooCommerce Site Kit event provider script was present
• the custom PDA GA4 Purchase Fix MU plugin was disabled

We also used a temporary diagnostic filter and confirmed that googlesitekit_analytics_tracking_disabled was already receiving true as its input value, with no external callbacks modifying it.

After disabling the Site Kit option that excluded all logged-in users from Analytics tracking, the ga-disable-G-W842EZ2B1Z snippet disappeared from the order-received page.

I then placed a new test order and the purchase event appeared correctly in the GA4 Realtime report.

So the issue is now resolved.

Thank you very much for your help and for guiding me through the troubleshooting process.

Hi,

I completed the additional checks you requested.

On the order-received page, I ran:

Object.keys( window.google_tag_manager || {} )

The output contains, among others:

GT-NSKG5NZV
AW-18428267882
dataLayer
ads_pageview
dedupe_gclid

So both the GA4/Google tag and the Google Ads tag appear to be loaded.

In DevTools > Network, filtering for collect, I can see multiple requests, including requests associated with AW-18428267882.

When filtering for:

measurement.php

no requests are shown.

Google Tag Gateway is currently disabled on this site, which may explain why there are no measurement.php requests through the site domain.

I also checked the MU plugins. PDA GA4 Purchase Fix is still active and is located in /wp-content/mu-plugins, so it is being executed automatically.

I have screenshots showing:

• the google_tag_manager output
• the collect requests
• the empty measurement.php filter
• the active PDA GA4 Purchase Fix MU plugin

Please let me know whether you would like me to temporarily disable PDA GA4 Purchase Fix and repeat the purchase test, or whether you would prefer another test first.

Hi,

I completed the additional tests you requested.

First, on the order-received page I ran:

JSON.stringify({jquery: typeof window.jQuery, gtagEvent: typeof window._googlesitekit?.gtagEvent, events: window._googlesitekit?.wcdata?.eventsToTrack, hasPurchase: !!window._googlesitekit?.wcdata?.purchase, purchases: window.dataLayer.filter(e => e[1]==='purchase').map(e => e[2]?.event_source ?? e[2]?.send_to)})

The output was:

{"jquery":"function","gtagEvent":"function","events":["add_to_cart","purchase"],"hasPurchase":true,"purchases":["AW-18428267882/3u0LCPbctO4cEOqapNNE","G-W842EZ2B1Z","site-kit"]}

I also checked the page source and found the WooCommerce Site Kit event provider scripts. The source includes:

googlesitekit-events-provider-woocommerce-js-before

and

googlesitekit-events-provider-woocommerce-js

The surrounding source also shows:

window._googlesitekit.wcdata.eventsToTrack = ["add_to_cart","purchase"];

I have added the new screenshot to the same Google Drive folder:

Please let me know what you would like me to test next.

Hi Adam,

I completed the additional test with CookieYes completely disabled.

I then placed a new WooCommerce test order and checked GA4 / Tag Assistant again.

Unfortunately, the result is the same: the purchase event is still not being sent to Google Analytics.

So far I have now tested with:

• Google for WooCommerce disabled
• CookieYes disabled
• Site Kit as the only GA4 provider
• Incognito/private browsing
• a clean test order

page_view and add_to_cart continue to work, but purchase still does not reach GA4.

This appears to rule out both Google for WooCommerce and CookieYes as the cause.

Please let me know what you would like me to test next.

Thank you,
Antonio Massa

ok i did

Hi Adam,
I found one additional detail during the incognito Tag Assistant test.

The Google Ads tag AW-18428267882 does send a purchase conversion. Under “Hits sent”, Tag Assistant shows:
[82b1] Google for WooCommerce purchase action

However, for the GA4 tag GT-NSKG5NZV / G-W842EZ2B1Z, the same purchase event shows “No hits were sent by this tag.”

So it appears that Google for WooCommerce is successfully sending the purchase to Google Ads, while Site Kit is not sending the corresponding purchase event to GA4.

I’m attaching screenshots of both behaviors.

Hello,

I completed the conflict test.

I temporarily disabled all non-essential plugins, leaving active only WooCommerce, Site Kit, and the minimum required to complete a test order.

The MU plugin PDA GA4 Purchase Fix is disabled.

I then completed a new test order and checked GA4 Realtime.

Result:

• page_view is tracked
• add_to_cart is tracked
• purchase is still not being sent

So the issue persists even after the conflict test.

I had also already verified that:

• window._googlesitekit.wcdata.eventsToTrack contains purchase
• window._googlesitekit.wcdata.purchase contains the correct order ID, total, currency, shipping, tax, and items
• window._googlesitekit.gtagEvent exists
• the Google Tag loads correctly on the order-received page

However, the purchase event still does not appear in GA4 Realtime.

Could you please advise on the next troubleshooting step?

Thank you,
Antonio Massa
