I have just installed version 1056 and converted the database to 1055 (upgraded from 1054 to 1056). When I select the diary I receive an error and the diary wasn’t working anymore. I sent the bug-report through the application.
Luckily I did a backup of the database before I ran the upgrade, so now I am back to 1054 and did a database restore and all works again.
Please report what could have caused this.
