mysqli object is not fully initialized - Joomla (1 reply)

Hello,

I am experiencing an issue after installing WAMP and trying to use Joomla on the localhost. I use awardspace as a hosting service. I have started a website and downloaded all the files from awardspace and placed them in www folder within the WAMP folder.
When clicking on the project I get

'mysqli object is not fully initialized'

Error
in C:\wamp64\www\datagrab.onlinewebshop.net\libraries\vendor\joomla\database\src\Mysqli\MysqliStatement.php (line 138)

        $this->connection   = $connection;        
        $this->query        = $query;        
        $query = $this->prepareParameterKeyMapping($query);        
        $this->statement  = $connection->prepare($query);        
        if (!$this->statement) {            throw new PrepareStatementFailureException($this->connection->error, $this->connection->errno);        }    }

and

mysqli_sql_exception
php_network_getaddresses: getaddrinfo for *****.runhosting.com failed: No such host is known.

               $this->options['ssl']['cipher']            );        }        
                // Attempt to connect to the server, use error suppression to silence warnings and allow us to throw an Exception separately.        
                $connected = @$this->connection->real_connect(            
                $this->options['host'],            
                $this->options['user'],            
                $this->options['password'],            null,            
                $this->options['port'],

I am not an expert in sql but seems like some connection error due to permission but no idea how to fix it.
I ll appreciate any help thank you
