What does it mean when I see the message "No value passed for parameter 'siteSlug'" after adding my GA Measurement ID in Webflow and saving changes, and could this be related to using a .studio domain for my website?

TL;DR
  • Verify Google Analytics Measurement ID is correctly entered without extra characters in Webflow.
  • Ensure the Custom Domain is configured correctly with Webflow’s IPs and set to ‘Default’ if using a .studio domain.
  • Confirm all necessary slugs and settings are completed in Webflow’s Site Settings.
  • Contact Webflow Support if issues persist.

Seeing the message "No value passed for parameter 'siteSlug'" indicates a potential issue in your Webflow settings after adding your Google Analytics (GA) Measurement ID. This might be related to incorrect settings or a problem with your current domain setup, including the use of a .studio domain.

1. Verify Google Analytics Integration

  • Ensure that you've entered the correct Google Analytics Measurement ID in the Project Settings under the Integrations tab.
  • Double-check that there are no extra spaces or incorrect characters surrounding your Measurement ID.

2. Check Domain Configurations

  • Ensure that your Custom Domain is properly configured in your Webflow Project Settings. This includes making sure your .studio domain is correctly pointing to Webflow’s IP addresses: (a) 75.2.70.75, (b) 99.83.190.102.
  • Verify that the .studio domain is set to ‘Default’ within your hosting settings if you are publishing to this domain.

3. Webflow Site Settings

  • Check if you have properly set up the site slug for your project. This might be under the Site Settings, where you name your project.
  • Ensure all required fields are completed in the General Settings to avoid backend errors, including slug-related issues.

4. Contact Webflow Support

  • If the problem persists after verifying the above, consider reaching out to Webflow Support for assistance as it may be specific to your account or project setup.

Summary

To fix the "No value passed for parameter 'siteSlug'" error after adding GA Measurement ID, ensure the Measurement ID is entered correctly, check domain configurations—especially if using a .studio domain—and verify Webflow site settings for the presence of all necessary slugs and fields. If unresolved, consult Webflow Support.
