Just in case this relates to a user configured page of a page which got corrupted configuration and you are trying to access the configure page again with the restoring link
You could to list page with a user ID whose configuration page is not corrupted and get the link address from there
Copy the link location to a text editor.
That is not going to be a proper URL right away, but you should be able to see what you need from there.
