[Plugin: Simple Twitter Connect] Authorisation not working out

Hi there, I’m testing STC and somehow there is something going wrong with the twitter authorisation. When I click the button, login to twitter and give authorisation it returns me to a white screen and the site url has a long string similair to – ?oauth_token=u8awpxvEqyqcA1X9IBRNO8VJ2 behind it. I’m using it on a clean install, not any other plugins installed and tested with themes twentyten and twentyeleven. I set up the twitter application according to the help screen, though ‘ browser’ or any type is not a choice anymore when creating a new twitter application. Any help would be greatly appreciated.
