[horde] Can't log in to IMP...

[Michael Robinson]

A fatal error has occurred
IMP_Imap: Invalid method call "getParam".

My backends.local.php must still be wrong :-(

[root at xerxes config]# cat backends.local.php 
<code>
<?php
        $servers['imap']['hostspec'] = 'mail.robinson-west.com';
        $servers['imap']['hordeauth'] = false;
        $servers['imap']['disabled'] = false;
        $servers['imap']['protocol'] = 'imap';
        $servers['imap']['port'] = 143;
        $servers['imap']['secure'] = false;
?>

I'm trying to do clear text login right now, though the password file
on the dovecot 2.x server is in cram-md5 format.  In evolution for
example, I have to specify cram-md5 instead of password.  Am I getting
the Invalid method call error because I'm missing something in
backends.local.php or am I getting it for some other reason???
