I’ve been having the same issue, and many other people reporting the same behavior with 6.0.3
Integration with reCaptcha seems to be broken. I will send it successfully when I remove the reCaptcha keys. After, re-adding, it stops. It was working fine until 2 days ago, on 6.0.2
I’ll rollback to 6.0.2 and disable auto-updates. Getting a lot of spam now because of this issue.
Please, patch ASAP.
What other plugins and theme do you use on the site?
Edit: I thought you were replying to my post. Sorry.
