Unknown database 'mfbp38mp_casaitalia_tv'

Cannot select database

The database server could be connected to (which means your username and password is okay) but the mfbp38mp_casaitalia_tv database could not be selected.

Are you sure it exists?
Does the user mfbp38mp_casaitalia_tv have permission to use the mfbp38mp_casaitalia_tv database?
On some systems the name of your database is prefixed with your username, so it would be like username_mfbp38mp_casaitalia_tv. Could that be the problem?

If you do not know how to set up a database you should contact your host. If all else fails you may find help at the WordPress support forums.
