There did you get this error, from your browser on index.php?

[Jason Lee]

Yup, it show on the index.php.

I found out in classes/Tools.php have this following code, can i remove it?

static public function displayError($string = 'Hack attempt', $htmlentities = true)
{
global $_ERRORS;

if (!is_array($_ERRORS))
return str_replace('"', '"', $string);
$key = md5(str_replace('\'', '\\\'', $string));
$str = (isset($_ERRORS) AND is_array($_ERRORS) AND key_exists($key, $_ERRORS)) ? ($htmlentities ? htmlentities($_ERRORS[$key], ENT_COMPAT, 'UTF-8') : $_ERRORS[$key]) : $string;
return str_replace('"', '"', stripslashes($str));
}
