[horde] Empty sidebar

[Luis Felipe Marzagao]

Hello:

Just installed horde via pear in a fresh ubuntu server. Everything went 
well. Test page shows no erros.

When I load horde to start configuration, I get an empty sidebar. Top 
menu icons are ok. Then I go to horde/admin/config and I can configure 
all settings. conf.php file saves just fine, but I still get empty 
sidebar. I tried to logout and login, after configuring sql based 
authentication system, just for testing, and the sidebar stills empty.

I set logging to DEBUG, but I see no errors. The only errors showing are 
pear´s packages "Assigning the return value of new by reference is 
deprecated", which I believe is harmless.

Horde (horde) 4.0.13
php 5.3.6-13
("You are running a supported version of PHP", says test page)

Any help?

Thanks,

Luis Felipe
