On my STC config screen, I see only these three fields:
* Consumer key (filled in)
* Consumer secret (filled in)
* Twitter default button
I assume there should be a list of modules like with Simple Facebook Connect but that is not a case. Maybe this plugin is not compatible with 3.3.1? Or am I doing something wrong?
One thing to note: in the instructions, there is this step: "Use Twitter for login must be checked (enabled)." Where do I enable this? Haven't found anything like that on dev.twitter.com settings page so maybe that's the problem?
