When you say "blank", what do you mean? Remember that it's a binary
file, so "cat" or "vi" are liable to spit out garbage or nothing.
Can you post an "ls -l" of it? It should look something like this:
[root@(protected) ~]# ls -l /var/log/wtmp
-rw-rw-r-- 1 root utmp 364416 Jun 27 15:42 /var/log/wtmp
