Hi All,

I am stuck in a rake migrate here, can any one help me?

Here’s how the problem goes;  
we added a new table in the application,our rake broke when we  
migrated the new tables. We got the following error:

oepfo@trex [~/railsapp/config]# rake db:migrate  
(in /home/coepfo/railsapp)

```
*****************************************************************
* config.breakpoint_server has been deprecated and has no effect.

```

- 

* * *

rake aborted!  
undefined method `template\_root’ for ActionController::Base:Class

We figured out the difference in rails version but we are not able to  
figure out the problem.

We are deploying the application in the production environment

Thanks

Saurabh
