Which version of CI are you using? This is how show_error function signature looks like in my CI 1.7.0

Code:

/**
     * General Error Page
     *
     * This function takes an error message as input
     * (either as a string or an array) and displays
     * it using the specified template.
     *
     * @access    private
     * @param    string    the heading
     * @param    string    the message
     * @param    string    the template name
     * @return    string
     */
    function show_error($heading, $message, $template = 'error_general')
    {
           ......
        }
