When I tried to upgrate wordpress last week to version 3.1.1. (dutch), I got 3.1.2.alpha(Dutch). WordPress gives me now the opportunity to install the stable 3.1.1 english version(wordpress detect I have the 3.1.2. alpha version). When I try to update automaticly the dashboard says “succesfully updated” but still shows I have the dutch 3.1.2.alpha version. How can I handle this?
