If an error message saying "Error: DOMAINNAME is not a valid domain. Please add it to the cookie consent manager to authorize the domain." appears in the browser's developer console, there are a few possible causes:

1. Problem: The URL (location.host) doesn't match the domain name listed under your Cookiebot account.
   Solution: Ensure that the domain is listed in under your Cookiebot account and that it is an exact match to the URL.
   
   
2. Problem: The CBID is incorrect or doesn't belong to the domain group under which the domain is listed.
   Solution: Ensure that the CBID on the Cookiebot script tag matches that of the Domain Group under which the domain is listed.
   
   
3. Problem: Your subscription fee is in arrears.
