CleanTalk was working fine. I don't know what changed, but now whenever I try to submit my Contact Form 7, I see this message:
*** Forbidden. Please enable JavaScript. Antispam service cleantalk.org. ***
Javascript is enabled. All form types are enabled in CleanTalk's settings.
When CleanTalk is deactivated, the message doesn't appear, and the form content is emailed to me as expected.
I've tried deleting CleanTalk and reinstalling it. No change.
What could be causing the problem?
