Last night I started an automatic update from within the wp-admin (2.7 I think to 3.1). After more than 1h of timeout, I decided to perform the update manually as the site displayed just a blank page (as it does now). Both update types led to the blank page and the HTTP500 server error thats being displayed now. I cant log into wp-admin and nothing is loading.
Please check http://www.tmtproject.eu for details.
Many thanks for any help!
