got it.
open file …/wp-content/plugins/floating-social-bar/class-floating-social-bar.php with your favorite html editor.
search for term (for me in line 1103)
data-send="false"
and replace false with true = should now look like this
data-send=”true”
now obviously the like space is not big enough and is cut by the bystanding g+ button. so you need to widen the space.
search for term (line 852)
fsb-share-facebook
and change the width from 120px to 190px. now looks like this
#fsb-social-bar .fsb-share-facebook { width: 120px; float: left; padding: 3px 0 2px; height: 25px; }
that’s it, have fun!
