I've downloaded from snaps: horde-2003-04-19.tar.gz imp-2003-04-19.tar.gz I've installed horde and it's all ok. I've installed imp but when I click on http://myserver/horde/imp/ I've a blank page. I've configured registry.php to auth with imp, servers.php and conf.php. Do you have a suggestion to solve my problem? Regards Paolo
