Visualize Your Sensor Readings from Anywhere in the World (ESP32/ESP8266 + MySQL + PHP)

Constant error with this app note, On Bluehost
Connection failed: Access denied for user ‘bill’@’localhost’ (using password: YES)
SQL Query
CREATE TABLE sensor_data (
id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
value1 VARCHAR(10),
value2 VARCHAR(10),
value3 VARCHAR(10),
reading_time TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP
)
I copy and pasted the text for both of the PHP files, Database name, username, and password verified multiple times.
$value1 = json_encode(array_reverse(array_column($sensor_data, ‘value1’)), JSON_NUMERIC_CHECK);
$value2 = json_encode(array_reverse(array_column($sensor_data, ‘value2’)), JSON_NUMERIC_CHECK);
$value3 = json_encode(array_reverse(array_column($sensor_data, ‘value3’)), JSON_NUMERIC_CHECK);
$reading_time = json_encode(array_reverse($readings_time), JSON_NUMERIC_CHECK);

http://example.com/post-data.php is functional

http://example.com/esp-chart.php fails with access denied

I have repeated Bluehost cpanel configuration 4 separate times, every attempt fails
on the esp=chart test.

Suggestions ?
