Hello,

Thanks for your reply.

I did as you said and created a database on the server. I also wrote down the same data in step 1. But I still get this error:
Warning: mysqli::__construct(): php_network_getaddresses: getaddrinfo failed: Name or service not known in /home/vhosts/r-o-v.nl/httpdocs/res/x5engine.php on line 4421

Warning: mysqli::__construct(): (HY000/2002): php_network_getaddresses: getaddrinfo failed: Name or service not known in /home/vhosts/r-o-v.nl/httpdocs/res/x5engine.php on line 4421
Unable to connect to DB

website: http://www.r-o-v.nl/imlogin.php

Does anyone know how to connect it properly?

The servers makes use of MySQL 5.6
