Hello, Since the migration from Plesk 7.5.3 to 7.5.4, i can't login to horde ! (all accounts). Whenever one of my accounts logs into their webmail they get a blank page on "http://webmail.domain.com/horde/imp/redirect.php" and they return to login page. The logs tells : Sep 06 08:38:43 HORDE [error] [imp] FAILED LOGIN xx.xx.xx.xxx to localhost:143[imap/notls] as firstname.lastname@example.org [on line 247 of "/usr/share/psa-horde/imp/lib/Auth/imp.php"] Please help !!
