[... sorry wrong thread. this is your site one :)]
have you corrected the DB_PREFIX...
open the database a3984309_czarnio
Do you have a table in there with the name DB_PREFIXsettings
if not, what is the 'settings' table called.
You need to edit the DB_PREFIX value to the same as the name on the 'settings' table.
PHP will add a global variable to the name of the table name: thus allowing you to share one database between many php/mysql applications.
IE: phpNuke and phpBB can share a database by having a nuke_ and phpbb_ prefix respectively, although both have a "settings" table, this prefix allows you to prevent overwriting data incorrectly!
