Position icon flag

Hello again realloc,
I need your help on another problem i am experiencing. I was not using a child theme and i updated my theme so i lost all the edits i have done. I am saying that because i have managed to position flag icon to my site (before the update) where i wanted, but now i am stuck cause i don’t remember exactly the edits i did.

Here is where i want the icon to appear (i have edited the image):
http://alevrasp.gr/wp-content/uploads/2014/03/position-icon-flag.jpg
I know that i need to edit the header.php with the following line:
<?php if ( function_exists( 'the_msls' ) ) the_msls(); ?>
but instead of displaying it in the position i want, it displays it on the top top left on the black background color.
That’s my site: http://alevrasp.gr/
If you open that link you will see it in the bottom left of the page because i am using the widget provided.

Thanks for your time!
