Question

Answer 1

This sounds as though the BOOMR object may not be loaded or at least is not loaded correctly or fully.

In the browser Console look to see what is returned when you type BOOMR and press enter. If the BOOMR object isn't there then you'll need to investigate what could be blocking it. Since this is browser and environment specific, I recommend looking for JS errors in the console fist.

Another possibility is that the BOOMR object is not loaded early enough and whatever code is calling the BOOMR.hasSentPageLoadBeacon is trying to execute the method before the object is loaded.

I'd also ensure that you are using the latest version of the BOOR library to make best use of its latest features and compatibility updates.
