Can't create/modify Twitter application


I was trying to create a Twitter application and always got the same error saying
"The form was outdated. Please copy any unsaved work and reload this page".

I’m on Mac OSX 10.9 and used Google Chrome and Safari.


I am trying to add or change an APP but it all failes “Copy any unsaved work in the form below and then reload this page.”

Is something wrong with the OAuth?
