[horde] Login.php - Blank Page

[avrodriguez at jusbaires.gov.ar]

Hi List!

Today made a update of Horde way cvs, but when I tried sign in in the
page "Login.php", I see the page in blank, rather I don't see the
form the login and password.

I checked the messages of Log, but I don't see any problem; my browser
  doesn't shows me problems(for example errors in Javascript).

What's the problem?

I have installed:

Apache/2.2.3
Php 5.2.0
Horde  4.0-cvs
kronolith H3 (3.0-cvs)



Thanks in advance for your help, Alexa
