Blank screen after installation

[Sascha K. Manns]

Hello Group,

I have installed Sonarqube with this howto: http://dev.mamikon.net/installing-sonarqube-on-ubuntu/. Also i have done all optional steps there.

But now, if i'm starting Sonarqube, a Browsertab with localhost:9000 results into a blank screen.

The sonar.log says:

The mysql service is running, and also the database "sonar" exists and is healthy.

Maybe anyone knows how to locate the problem?

Hi Ann,
