GA-4 Analytics [Support Thread]

**lat9** · 13 Feb 2025, 03:05 PM

v2.0.1 of GA4 Analytics is now available for download: https://www.zen-cart.com/downloads.php?do=file&id=2368

This version correctly update various configuration settings when upgrading from a non-encapsulated version of the plugin (#28).

I'm getting this on a new install of ZC 2.1

--> PHP Warning: Undefined array key "products_name" in xxxx zc_plugins/GA4/v2.0.1/catalog/includes/classes/observers/ga4AnalyticsObserver.php on line 741.

I'm going to turn it off.. I see where it's supposed to get it on line 741.. not sure why it is not getting it.

A copy of the full log with the backtrace information would help a lot, since it's the calling path that's introduced the issue.

This bug has already been reported here:

https://github.com/lat9/ga4-analytics/issues/29

**nicksab** · 3 Apr 2025, 12:42 AM

ZC 2.0.1 with GA-4 analytics version 1.2.4

Not sure if it normal behavior or a bug but when looking the page source of main page, it appears the script is being loaded 2 times. Site is at www.royal-fleur(dot)com for reference

Code:

<html dir="ltr" lang="en" prefix="og: https://ogp.me/ns# fb: https://ogp.me/ns/fb# product: https://ogp.me/ns/product#">
  <head>
  <!-- Google tag (gtag.js) -->
<script async src="https://www.googletagmanager.com/gtag/js?id=G-JQL28SP4BW"></script>
<script>
    window.dataLayer = window.dataLayer || [];
    function gtag(){dataLayer.push(arguments);}
    gtag('js', new Date());
    gtag('config', 'G-JQL28SP4BW');
</script>
 <meta charset="utf-8">
<!-- Google tag (gtag.js) -->
<script async src="https://www.googletagmanager.com/gtag/js?id=G-JQL28SP4BW"></script>
<script>
    window.dataLayer = window.dataLayer || [];
    function gtag(){dataLayer.push(arguments);}
    gtag('js', new Date());
    gtag('config', 'G-JQL28SP4BW');
</script>
    <link rel="preload" href="https://code.jquery.com/jquery-3.7.1.min.js" integrity="sha256-/JqT3SQfawRcv/BIHPThkBvs0OEvtFFmqPF/lYI/Cxo=" crossorigin="anonymous" as="script">

Is this normal behavior? If not how can i fix it?

Would upgrading to the latest version help? I am on ZC 2.0.1 so it may not be compatible.

Thank you for your time and help

You'll need to find which of the Google Tag Manager IDs belongs with the current site and remove the non-current.

While it probably doesn't affect site performance, Google does not recommend having more than one gtag.
