Is that your blog ? Do you have access to the Mysql Database ? If yes, look into the *yourprefixe*users for the proper login name. (Second column, just after ID, usualy).

ok. Fetch your login and password of the mysql database (you should have had to input them in the config file, if nowhere else).
Go to your hosting zone’s administration, find your way to the database interface (you will certainly have to login). Have a look at the table with the name *prefixyouchoose*users, each line of this table is one use. The second or third information on “your” line is your login. Passwod is encrypted, but since you have it…
