twitter login doesn't work

edit

unfortunately that didn't do the trick for my setup. I haven't done any customization or anything. out of the box pretty much. I still get the same url after I click "authorize app" and I get a 404 on twitter. I'm trying to figure out where does it pick that url that has the "api.twitter.com" instead of the "domain.com" in the url. thank you for the help so far !

Well, I am not an expert, it is my first time that I am creating such an application. But what I can see is that in your twitter application, there is a tab (the 3rd tab) with name OAuth Tool. You can find there a setting with name Request URI. The default value there (in my case at least) is https://api.twitter.com/1/ that looks like what you describe. But I haven't changed that.

thanks for your efforts mate but I still get the same problem.. and it's pretty much out of the box so I can't think I've done something wrong.. Usually those kind of things are getting done in few minutes , first time I had to hassle around that much.. anyway I'll keep on troubleshooting and I'll let you know if I succeeded something.. thanks again for your support Alexandros
