Warning: mysqli_query() expects parameter 1 to be mysqli, boolean given inC:\xampp\htdocs\shazz\include\main_content.php on line 4

The error and the code that you posted don't match. The connection string for mysqli looks like this:

 

mysqli_connect("myhost","myuser","mypassw","mybd")

So the error Access denied for user ''@'localhost' to database 'shazz' meens that the "myuser" parameter is empty, not the "mypassw" as you show in your code.
