Google Sitemap not generating completely

Silverstripe Version: SS5.3

Question:

I have the Google Sitemaps module GitHub - wilr/silverstripe-googlesitemaps: Google Sitemaps module for the SilverStripe CMS installed and it was previously working fine.

Now, when visiting https://mysite.ddev.site/sitemap.xml it displays as a blank white page (likely due to the xml being incomplete).

In the browser web inspector I get:

<?xml-stylesheet type='text/xsl' href='http://mysite.ddev.site/sitemap.xml/styleSheetIndex'?>

I thought the problem might have something to do with a module I’d installed or config change. I’ve stepped through a completely new install, and it works fine with all the same modules installed as on my site. Same with the config.

In the test install I get the following in browser web inspector:

Short of regenerating every single page in the SiteTree (there’s over 100), I’m at a loss how to debug this. There is no error logged anywhere and I have the following set in _config.php

ini_set('display_errors', 1);
error_reporting(E_ALL);

Any help with figuring this out would be much appreciated!

Ok. Have worked it out.

It’s due to the Google Tag Manager Module I have installed:

github.com/DorsetDigital/silverstripe-simplegtag

Interferes with wilr/silverstripe-googlesitemaps

bug

I've recently added this to a project and it all works great. However, I've n…oticed today that the sitemap module, [wilr/silverstripe-googlesitemaps](https://github.com/wilr/silverstripe-googlesitemaps) seems to have issues with it. The gtag code is being injected into the stylesheet which seems to be causing an error, and produces just a whitescreen when viewing the sitemap.xml page. **/sitemap.xml/styleSheetIndex** ``` <?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet version="2.0" xmlns:html="http://www.w3.org/TR/REC-html40" xmlns:image="http://www.google.com/schemas/sitemap-image/1.1" xmlns:sitemap="http://www.sitemaps.org/schemas/sitemap/0.9" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output method="html" version="1.0" encoding="UTF-8" indent="yes"/> <xsl:template match="/"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <link rel="dns-prefetch" href="www.googletagmanager.com"> <script>(function(w,d,s,l,i){w[l]=w[l]\|\|[];w[l].push({'gtm.start': new Date().getTime(),event:'gtm.js'});var f=d.getElementsByTagName(s)[0], j=d.createElement(s),dl=l!='dataLayer'?'&l='+l:'';j.async=true;j.src= 'https://www.googletagmanager.com/gtm.js?id='+i+dl;f.parentNode.insertBefore(j,f); })(window,document,'script','dataLayer','GTM-XXXXXX');</script> <title>XML Sitemap</title> <link rel="stylesheet" href="/resources/vendor/wilr/silverstripe-googlesitemaps/css/style.css?m=1712549048" /> </head> <body> <noscript><iframe src="https://www.googletagmanager.com/ns.html?id=GTM-XXXXXX" height="0" width="0" style="display:none;visibility:hidden"></iframe></noscript> <div class="content"> ... ``` **Google Chrome Dev Console** ![image](https://github.com/user-attachments/assets/b05f44b4-35ad-44ff-8c67-475def811062)
