There appears to be a bug with jetpack comments (via the social login) and recaptcha.
(i tried twitter and facebook comments with those social logins)
It is saying that there is an incorrect captcha value , but there is no actual showing of a recaptcha on the page (screenshot attached)
O.k. i have sorted it out… leaving on forum in case someone else has same problem.
I removed on recaptcha settings with geo directory: the enable for geo directory comments and made disable. Now works fine with twitter and facebook.
