Access Logs and Counters not incrementing

Hi all, I finished my first drupal installation a few days ago but I'm having the problem that Access Logs and Counters are not incrementing. I have enabled the statistics module and both counters and access logs but just can't make the number grow ;).

Any ideas? btw I'm running drupal 5.1.

Thanks and sorry about my english.
