Redmine

I've migrated from redmine 1.3.4 to 2.4.5.

If I test redmine with webrick all goes fine:

ruby script/rails server webrick -e production

But If I start it with apache I get this error:

This is the full text of the error:

My production log is this:

And my environment:

I checked several similar posts with no luck, specially this one:

[[http://www.redmine.org/boards/2/topics/40864]]

But I checked my Gemfile and it's identical as [[http://www.redmine.org/projects/redmine/repository/entry/tags/2.4.5/Gemfile]]

Any suggestions?

Kind regards
