Restore not displaying

I have try to update the phplist and acidentaly i deleted the config file.
I’ve inserted the database name, user and password in a fresh config file but now instead of asking me to restore it display message “Database has not been initialised. go to Initialise Database to continue” like i was starting a fresh instlation. Any tips that can help me to solve this?
Thank you

@rochajorge phplist isn’t finding your tables. Possibly you also need to set these values if they were different

# if you want a prefix to all your tables, specify it here,
$table_prefix = 'phplist_';

# if you want to use a different prefix to user tables, specify it here.
# read README.usertables for more information
$usertable_prefix = 'phplist_user_';
