This page requires JavaScript to get the token. If you don't want to enable it, you can copy the text in the URL between access_token= and &scope.. instead and set it in Chatty using the command (close dialogs first so you can type stuff in):
access_token=
&scope..
/changetoken <paste here>
There is more information about this in the help. (Open the help in Chatty via Help - About/Help or press F1, then go to Guides / What to do when getting login fails.)
