Site DOES NOT LOAD after 3.1 update

I’ve had this same issue a couple of times now. Generally I’ve resolved it by manually downloading 3.1 and replacing the files in the directory. After the transfer is complete I was able to log in and update my database with the drop-down it presented.

Hata!: SQLSTATE[HY000] [1045] Access denied for user 'divattrend_liink'@'localhost' (using password: YES)
