Yesterday my GA plugin started playing up. The panel showing traffic data would not load [spinning wheel] but eventually showed the error: "Google_IOException thrown".
Today the panel loads but shows data from another website I own. But having checked the GA panel, the correct website is selected.
So what's changed...I upgraded to WP3.8.
The theme I'm using is 2010.
Have de-arthourised and reset GA.
Any advice appreciated.
