Hello,

I'm implementing a new installation of Redmine on Ubuntu 14.04 and Redmine 2.6.2. The installation was good since I could open the platform in a web browser using the Webrick HTTP server. However, when I try to hold Redmine into Apache 2.4.7 I got this error:

Web application could not be started¶

Is there someone who could help me with this problem?

Thanks in advance.
