Redmine

I used this method to install redmine http://martin-denizet.com/install-redmine-2-5-x-git-subversion-ubuntu-14-04-apache2-rvm-passenger/

I installed redmine in /opt/redmine, and i checked my log in /opt/redmine/current/log/production.log

My tail of production.log

Completed 500 Internal Server Error in 42.6ms

Everything seems to be working except for "My account" page.

I have found this problem other places, but no solutions

The file it's looking for doesn't exist, but I am lost as to the solution. Any help is appreciated.
