I am having an issue with my Rails localhost Server, all Post calls started returning 405 method not allowed. However there are no problems on our staging and production
Could you post your routes file and also the exact rails version of your dev-environment and the production servers?
I assume this could happen when you post to a route that is only registered as a get request (depending on your rails version) or maybe routes that are defined twice, e.g.:
resources :photos, :only => [:index]
get :photos
