Hi everyone,

I’ve been setting up a web application on my host (mediatemple) using  
the restful\_authentication with the guidance offered by a few help files  
and the video from Railscast. Everything went fine with the  
installation, configuration and database migration, but whenever I run  
it, this error pops up:

Processing SessionsController#new  
[GET]  
Session ID: 5c4c2fe4d0f72f51aef1bbe4e9b391a1  
Parameters: {“action”=\>“new”, “controller”=\>“sessions”}

ActionController::MissingTemplate (Missing template  
/home/xxxxxx/containers/rails/beta/app/views/sessions/new.rhtml):

Now when I flip over to that directory, I have:

:/home/xxxxxx/containers/rails/beta/app/views/sessions$ ls  
new.html.erb

Is there some missing file association that I need to setup or ?

What version of rails are you running on? Rails 2.0 uses the new  
extensions  
of .html.erb which indicates that it’s in a HTML format written in ERB,  
where as previous versions of rails still use the old .rhtml extension.  
You  
may have to rename the file to .rhtml.
