Hello, I ran the latest version of Joomla (3.6) and K2 (2.7.1).
On the registration page, Recaptcha loads about 2 every 3 page refreshes: www.ravopleko.gr/eggrafi-xristi

When Recaptcha does not load, user cannot register and an error shows up - user has to re-enter registration info.

Thanks!

I forgot to mention that I disabled Joomla Recaptcha plugin.
And on "Global configuration" I set Recaptcha to "None"!

Hello,

I cannot verify the issue, the link for future reference (for me :)) is www.ravopleko.gr/signup
