Recaptcha Anchor broken image on bottom left of my pages

I am seeing a Recaptcha image showing on the bottom left corner of all my pages. If I use the developer tools and roll over it I find it is a Recaptcha Anchor. It is displaying the following error message:

This site key is not enabled for the invisible captcha.

However, I am not aware of setting up my site for invisible recaptcha because I do not yet have it set up. I just checked Komento, EasyBlog and EasyDiscuss and see that invisible recaptcha is not enabled there. So, that seems to leave EasySocial but I have not found the Invisible Recaptcha setting. I am wondering if somehow I might have checked but but I sure do not remember doing so.

any pointers in the right direction will be appreciated.
