Hello,

I use Jetpack plugin and my site url is: http://xlomo.gr/site/
In main site if you go at the bottom of the page while hou haven’t logged in, there is a line with a smile sign on the left.
This appear only in you are not logged in.
Smile sign appear as i have Jetpack plugin activated.
If i will disable JetPack states than it will disappear.

Please, how can I disappear the smile?

Thank you.
