[imp] Sidebar/menu gone after login

[Sander Dalemans]

Hello,

A few weeks ago I did a daily update from CVS HEAD, after that the sidebar is
gone. I'm sending this to the IMP list because I use IMP as authentication
method for Horde.

Before logging in I’m at the URL /horde/imp/login.php, after logging in it sends
me to the /horde/login.php page with the Horde portal. I’ve asked a few other
users if they have still a sidebar, and they haven't to.

So, how can I get my sidebar back?

Some information about the server:
  Slackware 8.1
  Horde: 3.0-cvs
  IMP: 4.0-cvs
  PHP: 4.3.2
  Apache: 1.3.27


With kind regards,
