Cookie consent dialog does not appear

If the CookieHub consent dialog does not display on your site, it’s usually caused by an incorrect setup or a conflict with caching or security settings.

Possible causes:

  • CookieHub implementation code is missing or incorrect.
  • Google Tag Manager (GTM) changes not published.
  • Ad blockers or security plugins are blocking scripts.
  • Caching plugin or CDN serving outdated content.
  • Content Security Policy (CSP) preventing script execution.
  • Performance optimizations delaying script loading.

How to fix:

If using manual HTML implementation:

  1. Confirm that the CookieHub script is added exactly as shown in the Implementation tab of your dashboard.
  2. Ensure the code is placed at the top of the <head> tag.
  3. Clear any site or server cache and check again.

If using Google Tag Manager:

  1. Confirm that you published the container after adding the CookieHub tag.
  2. Make sure Additional Consent Checks are not added to the CookieHub tag.
  3. Use GTM preview mode to check if the tag is firing.

General checks:

  • Disable ad blockers and test again.
  • If you use a caching plugin or CDN, purge the cache.
  • If CSP is active, update your rules to allow:
https://cdn.cookiehub.eu
  • Disable any JavaScript optimizations (e.g., defer or async) for the CookieHub script.
