Redmine

Hello,

I need help on a redmine migration.

I migrate from 2.6 to a brand new server on the last version.

What I did is a new installation foolowing this link : http://www.redmine.org/projects/redmine/wiki/install_Redmine_25x_on_Centos_65_complete

Its ok and fonctionnal. I migrate the conf files etc...

Now i have exported the database by mysqldump and imported into the new one (same db and user name/pwd).

Seems ok but when I try to login i got a :
"Internal error

An error occurred on the page you were trying to access."

The only things I got on redmine logs is :
@Processing by AccountController#login as HTML
