On the preferences page, there are three preferences under the heading Statistics:
1. "Don't show me any hit counts."
2. "Don't show me hits on my works."
3. "Don't show other people hits on my works."
For the past few years, it's been the case that if you set any of these, it'll only work sometimes due to caching. These preferences should be removed.
This should almost certainly have a news post published ahead of time telling users how to create a custom skin that hides hit counts for themselves.
