The Visitors > Real-time report does not automatically refresh every few seconds (as we'd expect). When the page loads the following JS error is triggered early on:

Error: cannot call methods on liveWidget prior to initialization; attempted to call method 'started'

The Real-time report is displayed correctly once but does not refresh then.
Also, when clicking on the Pause/Play button at the bottom of the page, it triggers slightly different JS errors:

Error: cannot call methods on liveWidget prior to initialization; attempted to call method 'stop' index.php:4:1813
Error: cannot call methods on liveWidget prior to initialization; attempted to call method 'start' index.php:4:1813
