A fix has been proposed in #8094.

How are you running Flagsmith

• Self Hosted with Docker
• Self Hosted with Kubernetes
• SaaS at flagsmith.com
• Some other way (add details in description below)

Describe the bug

Google Tag Manager does not appear to be loading correctly on https://docs.flagsmith.com/.

The Docusaurus configuration currently defines GTM under themeConfig.tagManager using trackingID:

tagManager: {
  trackingID: 'GTM-5ZV5K5G',
},

### Steps To Reproduce

Go to Google Tag Manager or GA4 and check tracking of docs.flagsmith.com

### Expected behavior

The GTM container GTM-5ZV5K5G should load on the production documentation site so that the configured GA4 tag can collect analytics data.
