Thank you for your reply.
I see that cron is enabled on your server, but I was interested to know if cron is enabled in your WordPress installation.
As regarding the live traffic tool, with the latest update of the plugin, version 4.0.3, there is a background cron job that will be run every hour and it will clean up the extra entries from the live traffic table.
For this to work, it needs cron enabled on your WordPress installation. If cron is disabled, you can always use the "delete all" button from the live traffic page to delete all entries from the table.
Also, if this tool generates too much load on your database, we have added a setting in the settings page which you can use to disable the live traffic tool.
