[imp] Imp pages not coming up

[Ryan]

Greetings list,

I am having an interesting problem that I have been tough time resolving 
(even though I bet there is a simple fix). Although the main horde page 
will come up and lets me authenticate, no imp pages will come up (I get a 
'The page cannot be displayed' error).

I have searched the web, the mail-list archive, and all the logs on my box 
to no avail.

IMP is installed in the correct directory (www.mysite.com/horde/imp/). It 
even returned the imp specific error page when I had not copied the 
config/*.dist files to their correct name.

I am not using any databases, yet. The documentation does not say a db is 
needed, just recommended. So right now I am having users authenticate via 
IMAP.

Here is some information about my setup

Horde comes up fine.. I can login and authenticate correctly. After logging 
in the Mail options do appear.

/horde/test.php comes up and does not show any major errors (pear and php 
checks pass)
/horde/imp/test.php comes up and does not show any errors (and the imap 
test login works just fine)

HOWEVER.... any links that I click on for the e-mail just leads to a page 
error.

I don't have c-client installed. At one point I did, but results were the 
same. Would the problems I encountered be indicative of a bad c-client 
installation?

I am running qmail pop3 and smtp, as well as courier-imap (all these have 
been tested and work as they should).

OS - RedHat 7.3

Horde - 2.1
IMP - 3.1
