- If freeside-upgrade hangs, try stopping Apache, all Freeside processes, and anything else connected to your database, especially on older PostgreSQL versions.
- You may want to check your ACLs under Configuration->Employees->View/Edit employee groups and grant some of the new rights to one or more groups.
- Restart Apache and the Freeside daemons.
