So i created a new data base tha's  completly clear and i set the name dracon both username and database name and password qweasdr and i edited the config like this : 

$config['database']['type'] = 'mysqli';
$config['database']['database'] = 'dracon';
$config['database']['table_prefix'] = 'mybbu3_';

$config['database']['hostname'] = '%dracon';
$config['database']['username'] = 'dracon';
$config['database']['password'] = 'qweasdr';

and i get the following error,  so i dont really know what to do   and i am not really good at this  also i  used  one of my old project  (forum) 

error :

i mention that i dont have any backup of data base i started from 0 with the database ,

$config['database']['table_prefix'] = 'mybbu3_';

is the prefix mybbu3 correct ? do you have it as the prefix for the database tables ?
