I have used phpMyAdmin in the UniServer dashboard to create the
a User nzmotorh_markh
I have given nzmotorh_markh All privileges on database nzmotorh_forum.
I have imported my data into this database.
I can browse this data using phpMyAdmin
The forum's config.php is as posted in a previous post and I have attached some screen shots from within phpMyAdmin that seem to show (to me) that the config.php settings are right.
BUT when I try to run the forum's index.php I still get the following message
SQL ERROR [ mysqli ]
No connection could be made because the target machine actively refused it. 
An sql error occurred while fetching this page. Please contact an administrator if this problem persists.
