Troubleshooting
The banner does not appear
Check activation, published configuration, existing preferences, GPC, and browser loading errors.

If the consent banner does not appear, first separate an intentional state from a loading failure. A saved preference, disabled display mode, excluded page, regional rule, script error, or stale configuration can each suppress the interface. Reproduce the issue in a clean browser before changing settings.
Check display conditions
- 1.
Confirm the banner is enabled
Open Configuration and verify Enable Cookie Consent Banner is on and saved.
- 2.
Check the published state
Review the CDN publication time and allow for the short configuration cache.
- 3.
Test without an existing preference
Use a private window or remove
cellwall_consent_preferences. CookieWall does not automatically show the dialog when a saved choice exists. - 4.
Check GPC behavior
An active GPC signal can record the marketing opt-out without showing the normal first-visit dialog.
- 5.
Inspect browser errors
Look for a missing configuration, a failed CDN request, an absent Project ID, or content-security rules that prevent the bundle or configuration from loading.
