(400) Unknown metric(s): ga:timeOnSite 워드프레스 google analytics 오류시

The ga:timeOnSite metric was depricated back in April.

Metric – ga:timeOnSite – Use ga:sessionDuration instead.

In order to fix the chart on the dashboard you’ll need to edit the plug-in.

It’s line 454 in google-analytics-summary-widget.php, just replace ga:timeOnSite with ga:sessionDuration and it will work again.

즉 ga:timeOnSite  대신 ga:sessionDuration  으로 교체하면 됩니다.
