I installed wordpress on my own domain and everything went smoothly until I decided I didn't want the url to my blog to have "wordpress" in it. I wanted something more fitting instead so I tried changing the name of the wordpress folder in my ftp, but with this the site stops working. Changing it back to "wordpress" again, everything works fine.
There was a setting where you could change this on the dashboard, but as soon as I tried this the wordpress powered part of the site breaks down. Now I can't even reach my dashboard to undo the change, even if I re-install wordpress manually.
