In the admin menu we now have a blank div where we used to have a graph.
I inspected the javascript and can see this binding:
$("div#placeholder").bind("plothover",function(event,pos,item)
It doesn't throw any exception, but when insepcting the XHR traffic I can see the call to
admin/admin-stats.php?type=hits
Instead of what I would expect should be JSON data or something, this contains only this:
"Unknown column 'd20170302' in 'field list'"
Where has our statistics gone? :-)
