So, do you have any idea. What should i do?

Answer 1

It looks like the problematic file uses the new hash syntax introduced with ruby 1.9. It looks like you are running the app with ruby 1.8 though.

1.) You could install and use ruby 1.9
2.) You could change the hash syntax of the file. Rails 3.2.9 should run with ruby 1.8.7 so hopefully this is the only problematic area.

The difference in the hash syntax is:

1.9

{key: 'value'}

1.8

{:key => 'value'}
