Ever since changing to 3.9, I've had the following problem.
Often, but not always, the Dashboard, Visits by country, Traffic Overview, then further down, Stats - Clicks, search terms, Post views, referrers - are all blank, like they've just disappeared. I've disabled Adblock Plus on this page so it can't be that.
Also, while I'm asking the question, Stats Social Media Metrics has never worked. It gives a fatal error.
Can someone help, please? I just tried updating to the latest version but to no avail.
