When I updated a url without protocol like www.errorpage.com in config settings. And tried to type a keyword which is not in DB. Then the pagee redirects to root domain like http://short.me/blah redirects to http://short.me

Also, if we mention the url with protocol like https or http://www.errorpage.com, and try to save the config which is forwarded to 403 error.

Let me know if i trying the option correctly. Also is there a way i can place a file called error.php or error.html in the same yourls folder and mention in the config file?

I've had version 1.0 of this plug-in installed and working for a very long time, but just today it dawned on me that I had configured a fallback URL but it's no longer working. I suspect this has something to do with http://diegopeinador.com/ dying.

Is there any chance you could release a new, working version of this plug-in?
