Hello,

When I try to boot my server by ruby script/server, it throws me  
following  
error:

Not sure what is causing this. Any pointers?

cache\_template\_extensions has been removed. expunge all traces of it  
from your app’s configuration

I had similar problems booting mongrel. Turns out I had my rails  
project in a sub folder. When I moved it back into the Ruby folder it  
booted up just fine. Hopefully thats all it is
