"Site not found" when using the URL http://<mysite.com>/taxonomy/vocabulary/<id>

http://www.example.com/taxonomy/vocabulary/xxx would be right, assuming this module is enabled on it. I can't point you to my live site right now because it's under a serious attack if I put it back online. But you can log onto it with your DO id. There will be a menu entry that will work, and you can see the URL there.

By any chance, do you not have "Clean URLs" enabled? If not, I think it would then be something like http://www.example.com?q=taxonomy/vocabulary/xxx

.
Please don't assign an issue to yourself unless you're providing a patch.

Go to http://nanwich.info/user (exactly that, which is also how you get into your site when you break it).

It will then show you the login boxes. Enter your ID here with @drupal.org) -- Pustefix@drupal.org and use the same password you have here. The module that allows that is a bit finicky, so it may throw some messages at you, but it will accept your login.

The demo site is working: http://nanwich.info/taxonomy/vocabulary/1+2
