I created a page view, but when I type in the address for it, it shows "Page not found". When I try to put the block where I want it to go, it doesn't show up, not even under disabled blocks. What step did I miss?
Are you sure you associated an URL with the view, or you are typing the correct URL?
If the URL requires a parameter (e.g., the node ID, the user ID), it is possible you entered a value that is outside the range of the possible values; for example, if the parameter is the node ID, and the higher node ID is 500, when you use 510 for that parameter, you would get a "not found" error message.
