Hi, I am using simple_captcha. It worked find until I add the following line to routes.rb match ":controller(/:action)", :constraints => {:controller => /sandbox\/[^\/]+/} The captcha image is not showing and the log shows the following error message. Started GET "/simple_captcha/8cdf70c193dc8823f281828f11c250e1739883da?time=1294644088" for 127.0.0.1 at Sun Jan 09 23:21:29 -0800 2011 AbstractController::ActionNotFound (The action ''8cdf70c193dc8823f281828f11c250e1739883da'' could not be found for SimpleCaptchaController): Why does the line in the routes affect simple_captcha?
