What's Next
Now that you've installed Consently via Zaraz, you should:
Troubleshooting
Banner not appearing after setup
Why this happens: Zaraz changes may take a few minutes to propagate, or the tool might be disabled.
Solution:
Wait 5 minutes and clear your browser cache
Check that the Consently tool shows "Active" status in Zaraz Tag setup
Verify the Enabled toggle is switched on in the tools list
Open your browser's developer console (F12) and check for any JavaScript errors
Banner appears twice
Why this happens: You may have Consently installed both directly in your site code AND via Zaraz.
Solution:
Check your website's HTML source code for duplicate Consently script tags
Remove any direct installations if you're using Zaraz
Keep only one installation method active at a time
Script shows "Invalid banner ID" error
Solution: Verify you copied the complete embed script from your Consently dashboard, including the correct data-bannerid attribute. The banner ID is unique to your site and must match exactly.
Changes to banner design not reflecting
Why this happens: Cloudflare's edge cache may be serving an older version of your banner configuration.
Solution:
Publish your banner changes in the Consently dashboard
Wait 2-3 minutes for the changes to propagate
Clear your browser cache and refresh the page
If the issue persists, purge your Cloudflare cache: Account → Select Your Domain → Caching → Configuration → Purge Everything
