Concrete5 has built in site statistics tracking but it’s very simple and records every hit, not checking if the user is unique. This can create some very large database tables and possibly slow down your website. Although the graph will remain in the dashboard, the site will no longer track all the visits.
Open up config/site.php and add the following lines:
// turn off site tracking define('STATISTICS_TRACK_PAGE_VIEWS', false);
As well, load up your favorite database manager, like phpMyAdmin and find the table PageStatistics and empty the contents to clean up past tracking data.
