Your new update creates security issues for the website. Some of the visitors on my website mentioned that they cannot open the website because the browser gives them this message:
"Security check: looks like you are a SPAM bot. If you think this is an error, please email the site owner."
I saw the message myself when I tried to open the site on iPad. I also saw that when I tried to use your google plus button. I disabled the plugin and the messages went away.
I do not know what you added to the plugin in the latest version but whatever it is it makes it unusable.
