Mysqli prepare error (1 reply)

Hi,

In the Visitors in Real-time panel on the Dashboard I'm getting the message:
Mysqli prepare error: 'sub.idsite' isn't in GROUP BY

This is a clean installation on an Ubuntu 12.04 server running PHP 5.4.23 & MySQL 5.5.35

Any suggestions what could be causing this or what I can do to diagnore the problem?

Thanks,
Richard.
