You need to add a note in the readme and the first post that this requires PHP 5.1.0 or higher. At least one function that you call (htmspecialchars_decode) requires that version or higher.

edit-------------------
Adding this code at the beginning of the ces_permissions.php file allows it to work on earlier versions of PHP:

if (!function_exists("htmlspecialchars_decode")) {
    function htmlspecialchars_decode($string, $quote_style = ENT_COMPAT) {
        return strtr($string, array_flip(get_html_translation_table(HTML_SPECIALCHARS, $quote_style)));
    }
}

It appears that HTML parsing is required for pre-parsed custom fields or anything with decent formatting. Would be nice if you could tell the system to ignore specific BBCodes.
