Wrong site showing error message

Hi.
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.

Cheers.
