can't log into the admin area

[mkreder]

My system is running Centos 5.5, Yesterday, I installed ispcp without any further issues, but when I try to log into the admin area (admin.xterm.com.ar) it doesn't work.
The issue is that if I log with the correct password, the login screen reappears, I get an email saying that I just logged in, but I'm not.
If I put a wrong password, it clarly say it's wrong.
I have taken a look into the database, and in the admin table, everything looks fine, I guess that the connection between ispcp is ok, because I get an email, but I don't know why it's redirecting me over and over again to the login screen.

I tried googling and googling and the only thing I found is this old bug, reporting something similar:

http://isp-control.net/ispcp/ticket/1978

But I don't recall to put in the very first time a wrong password, so it's not the same problem.

Checked all the logs under /var/log/ispcp/* and got nothing special. Tried to enable debug, with DEBUG = 1 in the ispcp configuration, but then the pages were not leagible for the browsers I'm using (chrome, firefox with cookies, javascript and everything enabled)

I don't know what do know, any help will be appreciated
