I did the following:
Please, reinstall the plugin with the Complete Deactivation option:
1) WordPress Admin Page —> Settings —> Anti-Spam by CleanTalk —> Advanced settings —> set the option “Complete Deactivation” to “On” —> Save Changes.
2) WordPress Admin Page —> Plugins —> Installed plugins —> Anti-Spam by CleanTalk —> Deactivate and then Delete.
3) Then install it anew: https://cleantalk.org/help/install-wordpress.
It didn’t fix the issue until I also deleted the plugin completely from my plugin list and re-added the plugin
Now it’s asking me to revalidate my email but it has no button to resend a validate email link so now I have this notification, lol.. :(.
