[SM-USERS] Invalid mailbox name

[Pierre-Luc D. <pld...@cy...>]

I've upgraded SquirrelMail and now it doesn't work. I'm using the same
configuration parameters than before, but I'm using new configuration files
(not the old ones, a brand new installation). I'm using standard IMAP (not
TLS) via courier-imap. My mailboxes are virtual, with mailbox names of the
format my...@my.... IMAP login seams to be ok, but I see these
errors in my browser when I log in:

Left frame:
ERROR : Could not complete request.
Query: CREATE "Array"
Reason Given: Invalid mailbox name.

Right frame:
ERROR : Could not complete request.
Unknown response from IMAP server: 1.Array0

I`m my Apache log file, I get errors like:
PHP Warning:  preg_match() expects parameter 2 to be string, array given in
/usr/local/www/squirrelmail/functions/imap
_messages.php on line 231

PHP Warning:  arsort() expects parameter 1 to be array, null given in
/usr/local/www/squirrelmail/functions/mailbox_di
splay.php on line 539

I'm running:
apache-2.0.52_4
php4-4.3.10
courier-imap-3.0.8,1

What i causing this error? How can I fix it?

Thanks!
