I have a problem with the Guestbook plus plugin. I am getting messages that v1 of captcha is shutdown. I redid my google captcha for this website and it's working fine for the contact form on the contact page but not the guest book form (http://dreaminstallations.net/Property_Maintenance_Westward_Ho_Bideford?cmd=sign) for people to leave comments. Anyone know how to fix that please?
The Guestbook Plus plugin is rather old and needs to be adapted to work with Typesetter's current reCaptcha (v2) implementation.
You might want to look up the code of FreeMailForm Enhanced to see how it works now (FeeMailForm.php + FreeMailForm_Gadget.php) and maybe eventually fix it yourself.
I updated this plugin to the Captcha 2 for myself some time ago. But it content some other adaptation and hard coded localization. If you want, look at this
