Hey there,
I am really sorry for the delay of this reply as it is a weekend for us here.
It seems like you have made some customisation for the Easysocial toolbar, can you check whether your current template got override this file or not?
JoomlaFolder/templates/rt_afterburner2/html/com_easysocial/toolbar/default.php
If yes, then you have to edit this file, find all this following code :
data-popbox-position="bottom-right"
Then replace with :
data-popbox-position="bottom-left"
If no any override file for this under your current template, you have to edit original file here
JoomlaFolder/components/com_easysocial/themes/wireframe/toolbar/default.php then override into
JoomlaFolder/templates/rt_afterburner2/html/com_easysocial/toolbar/default.php
