I upgraded to 2.7 manually and then when I logged in to see the (beautiful!!!) new dashboard I noticed there was still a notification at the top asking me to upgrade (I now know that this is because it hadn't yet had time to ping the wordpress server to confirm the upgrade). So I automatically upgraded (again) and the next time I went back to the dashboard I was horrified to see that everything was in Chinese!!!! How do I get it back to English?!?!
