ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

This error message indicates that the user 'root' tried to access a database on the localhost server but was denied access due to an incorrect password. This error can occur for several reasons, including:

1. Incorrect password: The password used to access the database is incorrect. Double-check the password and try again.

2. Incorrect username: The username used to access the database is incorrect. Make sure you are using the correct username.

3. Incorrect host: The user 'root' may not have permission to access the database from the current host. Check the host name and ensure that the user has the correct permissions.

4. Database permissions: The user 'root' may not have the necessary permissions to access the database. Check the user's permissions and grant necessary privileges.

To resolve this error, try resetting the password for the 'root' user or creating a new user with the necessary permissions. You can also check the MySQL error logs for more information on the cause of the error.
