I had issue with this smiles package so I tried to fix it works for me:
com_comment/joscomment/emoticons/SimpleSmileys/index.php
The changes are only removing spaces,example:
instead of I change to
<?php
$GLOBALS["JOSC_emoticon"][':)'] = "=).png";
$GLOBALS["JOSC_emoticon"][':D'] = "=D.png";
$GLOBALS["JOSC_emoticon"][':('] = "=(.png";
$GLOBALS["JOSC_emoticon"][':cry:'] = "cry.png";
$GLOBALS["JOSC_emoticon"]['>:('] = "angry.png";
$GLOBALS["JOSC_emoticon"][';)'] = ";).png";
$GLOBALS["JOSC_emoticon"][':|'] = "=!.png";
$GLOBALS["JOSC_emoticon"][':s'] = "=s.png";
$GLOBALS["JOSC_emoticon"][':p'] = "=p.png";
$GLOBALS["JOSC_emoticon"][';p'] = ";p.png";
$GLOBALS["JOSC_emoticon"][';D'] = ";D.png";
$GLOBALS["JOSC_emoticon"]['XD'] = "XD.png";
$GLOBALS["JOSC_emoticon"][':o'] = "=o.png";
$GLOBALS["JOSC_emoticon"]['-_-'] = "-_-.png";
$GLOBALS["JOSC_emoticon"]['^_^'] = "^_^.png";
$GLOBALS["JOSC_emoticon"]['>_<'] = "gah.png";
$GLOBALS["JOSC_emoticon"][':love:'] = "love.png";
$GLOBALS["JOSC_emoticon"][':3'] = "=3.png";
$GLOBALS["JOSC_emoticon"][';3'] = ";3.png";
$GLOBALS["JOSC_emoticon"][':\ '] = "=J.png";
$GLOBALS["JOSC_emoticon"][':cool:'] = "cool.png";
$GLOBALS["JOSC_emoticon"][':blush:'] = "blush.png";
$GLOBALS["JOSC_emoticon"][':thumbsup:'] = "thumbsup.png";
$GLOBALS["JOSC_emoticon"][':thumbsdown:'] = "thumbsdown.png";
$GLOBALS["JOSC_emoticon"][':x'] = "=x.png";
$GLOBALS["JOSC_emoticon"]['o_O'] = "o_O.png";
$GLOBALS["JOSC_emoticon"][':creepy:'] = "creepy.png";
$GLOBALS["JOSC_emoticon"][':greed:'] = "greed.png";
$GLOBALS["JOSC_emoticon"][':angel:'] = "angel.png";
$GLOBALS["JOSC_emoticon"][':devil:'] = "devil.png";
?>
This one
= "=J.png"; a little bit tricky for me
Hope its help.
