Get a blank page when trying http://api.twitter.com/oauth/authorize?oauth_token=XXX in browser


#1

I am using twitteR to get a PIN

API_key <- 'aaaaa’
API_secret <- 'bbbbbb’
cred = getTwitterOAuth(API_key, API_secret)

To enable the connection, please direct your web browser to:
http://api.twitter.com/oauth/authorize?oauth_token=XXX
When complete, record the PIN given to you and provide it here:

I am just cut & paste the URL to my browser (have tried Firefox, Safari, Chrome). All return a blank page.

Rgds,
Ricky
