I had to move a xenforo 1.1.5 install that I work on that I had to move to a sub-directory. The move, more or less, went fine. But some weirdness has happened in the transition. Some attachments can no longer be called up by the friendly URL and I can't figure out why. with the exception of being moved one directory down, the location's the same. The encrypted file name is the same in the database and on server. When I call the file up via the server's directory structure with the encrypted name, it shows up. The file's not corrupt. The check sum of the file is the same.
What might the problem be? Is it possible there's some database corruption? Could it be something else?
