These warnings indicate that there is an issue with the mysqli connection in the PHP code. The parameter being passed to mysqli_query() and mysqli_fetch_array() is null, which means that the connection to the database is not established properly.

To fix this issue, check the code for any errors in the mysqli connection. Make sure that the connection is established before running any queries or fetching data. Also, ensure that the correct credentials are being used to connect to the database.

If the issue persists, try restarting the server or contacting the hosting provider for assistance.
