If you are using Webalizer, the statistics are updated at 4 AM indeed.
So, for the first time, you have to wait maximum 24 hours.
After that moment, and if the stats are still not created, try these commands:
pkill cron (Make sure no cron processes are left.)
Edit your crontab (crontab -e) and save it again.
Then restart cron: /etc/init.d/cron start
This worked for me, when my webalizer was a little bit lazy some time ago.
