Hello, list.
Recently we upgraded our roundcube installation from 0.3.1 to 0.7.2 using standard procedure described in UPGRADING (installto.sh)
During update i was asked to update MySQL schema, so i agreed.
Right after upgrade i logged in to my box and saw that everything is fine, all subscribed folders were present. After clicking on several folders and verifing that i can read letters i moved to preferences (or settings, i'm using russian interface) and saw in folders tab that i have unsubscribed folders, after that i returned to mail screen and saw that some folders dissapered, after that i subsribed them again.
Seems that this bug affected some of users because people stated complainging that folders are disappearing from their email clients and roundcube roster.
Can anybody advice where i can start digging for solution? Should i inspect roundcubes MySQL DB or my imap server?
