Users are still having problems after the fix, I just now set the Cookies option to Off, lets see if the problems stop now. I don’t use a Caching plugin.

Hi,

Reinstalled the plugin but now some legit users are getting an error message “Forbidden. You sent forms too often”. But even after waiting the same message is displayed.

Yes, my site also got a lot of people blocked, and the worst part is no error message is displayed.

I also see it and since it has appeared, it seems to prevent emails from being sent to WP users randomly. I am using WP SMTP plugin to send emails via Google (transactional emails like password resets, user login etc) and since this red exclamation mark appeared a day back WP SMTP is unable to send emails. On clearing the cache the emails get sent but they again get prevented after some time.
