Did you run migration task to setup additional plugin?
Please re-confirm README or installation guide.

Periyanto, thanks for your confirmation.
I personally think more information of your environment, Redmine version, plugins list and so on would be useful to ask for help.

These informations are greatly helpful to support quickly, like creating issues.
You can get these informations from Redmine's information page.
(E.g. http://example.com/admin/info)

Redmine version
Installed plugins
Ruby version
OS Platform
Database (MariaDB, MySQL, PostgreSQL) and its version
Rails Env
