Hello, finally I got Horde set up for the first time. I'm useing Horde 2.2 and IMP 3.1. Login via IMAP works and access to the mysql database is also no problem. But I keep getting this warning, shown on all pages. Warning: Undefined property: _iv in /var/www/domains/mydomain/horde/lib/Cipher.php on line 107 Can anybody tell me what I missed? thx. Martin
