update of Editor-PHP-1.9.0 error Access denied for user 'xxxx'@'localhost' (using password NO

Hi

I have just transferred the latest version of the Editor software ( upgrade from Editor-PHP-1.8.1 to Editor-PHP-1.9.0 ) to my server and I am trying to view an example table on my server using the address

https://www.ukincomeinvestor.co.uk/Editor-PHP-1.9.0/examples/simple/simple.html

This is generating an error as follows

DataTables warning: table id=example - An error occurred while connecting to the database ''. The error reported by the server was: SQLSTATE[28000] [1045] Access denied for user 'ukincome'@'localhost' (using password: NO)

Do I need to make any changes to any configuration files to access the new directories to avoid this access error.

I know I will need to change my PHP scripts to reflect the new directory, but i need to overcome this error first.

Many Thanks

Colin
