Redmine

Hi
I just installed redmine on Centos7.
I added new project and at the project. Somehow, I do not see any new issue tab.
How can I add new issue? Is something missing here?

Environment:
Redmine version 3.0.2.stable
Ruby version 2.0.0-p598 (2014-11-13) [x86_64-linux]
Rails version 4.2.1
Environment production
Database adapter Mysql2
SCM:
Subversion 1.7.14
Git 1.8.3.1
Filesystem
Redmine plugins:
no plugin installed

I added more information here. When I run this command as required to get support, it is giving some errors. There could be a clue here

config.eager_load is set to nil. Please update your config/environments/*.rb files accordingly:

• production - set it to true
