Redmine

After migrating our Redmine instance from 1.3.3 to 2.5.2 version, we can't add notes on issues. When a authenticated user try to add note(s) on issue, when he update the issue, no error are shown (nor in log) and the notes aren't shown on history panel.

In our MySQL database, the changesets table is not populate correctly.
