Can not save user settings in Redmine 1.2

After upgrading Redmine to 1.2 I can not save email notification and language settings on "My account" page. I ran rake migrate, but that did not helped. What can cause that problem and is there any way to f开发者_如何学Cix it? Thanks a lot.

If you want to save your configuration, you can simply save the "email.yml" file (for email configuration) and "database.yml" (for database configuration).

These files are situated on :

<your_redmine_installation>/configuration/
