Jednoduchý plugin na logování IP adres návštěvníků. Po aktivaci vytvoří v databázi tabulku „wp_iplog_v1“, do které zapisuje: $_SERVER["REMOTE_ADDR"] //IP v4
$_SERVER["REQUEST_URI"] // cílová stránka
$_SERVER["HTTP_HOST"] // cílový web
$_SERVER["HTTP_USER_AGENT"] // user agent (os, browser, bot)
$_SERVER["HTTP_REFERER"] // referer
Plugin nemá žádné rozhraní, data jsou dostupná pouze z databáze.
Otestován na verzi WordPress 3.2.
