 * Looks like your PHP installation does not have the mbstring extension installed.
   See [http://www.php.net/manual/en/mbstring.installation.php](http://www.php.net/manual/en/mbstring.installation.php)
 * PS: A vote for my plugin would be a nice way to say thank you.

 * Thank you for your vote and for pointing this out. I will add some checks to 
   the code to make sure that function actually exists, before calling it. So that
   even those who don’t have mb_string installed, won’t experience this issue anymore.
 * Cheers,
    Camu
