Hi,
Sorry for the delayed response. We’ve heard of some similar cases, and it turned out to be other plugins conflicting with the WordPress 4.5 update — if any of them break javascript on a page where Wordfence uses javascript (including Live Traffic), then some of the functions on that page will not work.
Some of the problematic plugins are listed in the other post here:
https://www.ads-software.com/support/topic/live-traffic-not-working-v613
If you don’t see any of your listed there, the easiest way to identify the problem is to turn off other plugins temporarily, and enable them one-by-one until the Live Traffic stops working. (If you have any updates pending, the other plugins’ authors may have already fixed them as well.)
