[horde] Horde webmail edition questions . . .

[Spyros Tsiolis]

Hello again people,

OK, after a lot of ironing out, I managed to install Horde Webmail edition
on a CentOS5.4 box (Intel PIV @ 3.00Ghz/1Gb RAM/80Gb IDE/ATAPI HDD).

This specific installation is supposed to work with dovecot v1.2.9 but
that's another story.
After a lot of tinkering, I managed to get the following to work
(horde living under "/var/www/horde") :

http://server.ip.addre.ss/horde/test.php

It comes back with a lot of usefull info about horde.
However (here it comes :-), if I try to enter :

http://server.ip.addre.ss/horde and press <ENTER>, it shows this :

http://server.ip.addre.ss/horde/imp/login.php

on the browser command line and then nothing.

Horde Webmail edition v1.2.5 / mysql v5.1.41 php v5.3.1

Could someone please help me on this ? Is this a PHP error ? 
Would you require additional info ? If yes, please ask specifically;
I don't know what else to attach.

TIA,

s.
