Thema: Phoca Guestbook ich weiß nicht mehr weiter

Hallo,
bitte dringend um Hilfe. Ich habe xampp deinstalliert und wieder neu installiert. Joomla habe ich auch neu installiert. Es funktioniert immer noch nicht mit Phoca Guestbook. Ich kriege im Fronted nach dem Eintrag ins Gästebuch diese Meldung.

Warning: mktime() [function.mktime]: It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'Europe/Paris' for '2.0/DST' instead in C:\xampp\htdocs\jmika\libraries\joomla\utilities\d ate.php on line 117

ich hab einfach Phoca Guestbook und die deutsche Sprachversion von der eigenen Website runtergeladen, es hat geklappt.
