The error occurs because mysqli_select_db() requires two parameters: the database connection object and the database name. It seems your code is missing the connection object. Here’s how to fix it:
Correct Code
In global.php, modify line 13 to include the database connection object:
php
Copy code
mysqli_select_db($PowerCMSConnection, $database_PowerCMSConnection);
Explanation
$PowerCMSConnection should be your database connection object created using mysqli_connect().
$database_PowerCMSConnection should be the name of your database.
Additional Steps
Verify Connection: Ensure $PowerCMSConnection is properly initialized using:
php
Copy code
$PowerCMSConnection = mysqli_connect('hostname', 'username', 'password', 'database_name');
if (!$PowerCMSConnection) {
die('Connection failed: ' . mysqli_connect_error());
}
Check Configuration: Confirm that global.php has the correct database credentials and connection logic.
Database Import: If importing db.sql manually, ensure there are no errors during the import. Check for missing tables or permissions.
Debugging: If the error persists, add this line to debug:
php
Copy code
echo "Database connection: " . ($PowerCMSConnection ? "Success" : "Failed");
This should resolve the issue and allow you to proceed with the installation!
