It looks like that function is not enabled. Check your phpinfo() file for mbstring and see if its enabled. If you don't see it, it's not enabled.
If you are admin of your server, a first idea might be to check for something like
extension=mbstring
in your php.ini file.
Still not working?
Remove the entire sbwrap function.
 Codefunction sbwrap($text) {
global $locale;
$i = 0; $tags = 0; $chars = 0; $res = "";
$str_len = strlen($text);
for ($i = 0; $i < $str_len; $i++) {
$chr = mb_substr($text, $i, 1, $locale['charset']);
if ($chr == "<") {
if (mb_substr($text, ($i + 1), 6, $locale['charset']) == "a href" || mb_substr($text, ($i + 1), 3, $locale['charset']) == "img") {
$chr = " ".$chr;
$chars = 0;
}
$tags++;
} elseif ($chr == "&") {
if (mb_substr($text, ($i + 1), 5, $locale['charset']) == "quot;") {
$chars = $chars - 5;
} elseif (mb_substr($text, ($i + 1), 4, $locale['charset']) == "amp;" || mb_substr($text, ($i + 1), 4, $locale['charset']) == "#39;" || mb_substr($text, ($i + 1), 4, $locale['charset']) == "#92;") {
$chars = $chars - 4;
} elseif (mb_substr($text, ($i + 1), 3, $locale['charset']) == "lt;" || mb_substr($text, ($i + 1), 3, $locale['charset']) == "gt;") {
$chars = $chars - 3;
}
} elseif ($chr == ">") {
$tags--;
} elseif ($chr == " ") {
$chars = 0;
} elseif (!$tags) {
$chars++;
}
if (!$tags && $chars == 18) {
$chr .= "<br />";
$chars = 0;
}
$res .= $chr;
}
return $res;
}
and change
Code sbwrap(parseubb(parsesmileys($data['shout_message']), "b|i|u|url|color"))
to
Code parseubb(parsesmileys($data['shout_message']), "b|i|u|url|color")
