I created an API Token to use in the WP CF Cache plugin and when putting it in along with the correct email (copied from account details) and the domain, I get the following error:
Unauthorized to access requested resource (err code: 9109)
Tokens don’t use email addresses. Global API Key is paired with an email address, so it sounds like you have an incorrect authorization choice selected.
If that were the case, then I’m not sure why the plugin is asking for that information. The blank fields are filled in - wiped them out for security reasons. Are you saying to take them out and it should work?
