Upgrade (from cd) went smooth except for one thing: IMP webmail doesn't work anymore. error message: Fatal error: Failed opening required '../config/horde.php3' (include_path='.:/home/httpd/horde-phplib') in /home/httpd/html/horde/imp/login.php3 on line 21 I also run PHPGroupware, wich runs oke except for the mail function. Setting the mail retrieval for phpGroupware form IMAP to POP3 fixed the problem, so I guess something is wrong with IMAP. Otherwise, the prdocut is just great. Keep up the good work! Pieter
