Need help / rails 4.1.6

Hi,

sorry for abusing the pull-request feature, but there is in "issues" tab visible.

I can't get this gem working with rails 4.1.6 with " config.enable_multiparameter_extension! " enabled.
As soon I start the server, rails crashes:
 
=> Booting WEBrick
=> Rails 4.1.6 application starting in development on http://0.0.0.0:3000
=> Run `rails server -h` for more startup options
=> Notice: server is listening on all interfaces (0.0.0.0). Consider using 127.0.0.1 (--binding option)
=> Ctrl-C to shutdown server
Exiting
