In order to enable statistics, you have to turn on the Advanced features setting (enablestats). However, when Statistics not enabled, the Statistics settings page still appears at Settings > Site admin > Server > Statistics and the Course overview report appears in Settings > Site admin > Reports > Course overview.

We should consider hiding these two pages while Statistics is disabled.

Alternately we should consider making the following changes.

1. When you visit the Course overview report, while statistics is disabled, you are redirected to the Statistics settings page, you should instead be redirected to the Advanced features page, perhaps through a search for "enablestats".
2. When you visit the Statistics settings page, while statistics is disabled, you should see a notice that Statistics are disabled and provided with a link to the Advanced features page, perhaps through a search for "enablestats".
