  • Simple and effective CAPTCHA solution for Contact Form 7

    I have been using this plugin with Contact Form 7 and overall it works well. The setup is straightforward, and it helps reduce spam submissions without making the form too complicated for visitors. It integrates nicely with Contact Form 7 and does what it is supposed to do. For a free plugin, it is a very useful solution. I am giving 4 stars because there is still some room for improvement, for example in terms of documentation or additional configuration options. But overall, it is a solid and helpful plugin.

  • Beware: Blocks login

    Blocks login even if login protection is not checked in dashboard. Moreover, the right answer does not allow to login. You get locked out your own WP site.
