Test app Aouth



I own a twitter app that has worked - I think in May 2016, I ran it last time. I am a high quality printing house, I would like to introduce to everyone about our printing service, you will have the opportunity to own the beautiful business cards hcm, photobooks in the technical My quick print

However now when I run it I get the error:
Remote server returned error: (401) Not allowed.

Also when I go to my Twitter home page and click the “Check OAuth” button I get “Sorry, that page does not exist!”

I have not changed at all - why do I have to be able to figure out why it has limited activity?
