	Because of your password. You can see password validate configuration metrics using the following query in MySQL client:

	SET GLOBAL validate_password_length = 6;
	SET GLOBAL validate_password_number_count = 0;

	# Solution: stick this file up your repository root (which it assumes is
	# also the WordPress root directory) and add exceptions for any plugins,
	# themes, and other directories that should be under version control.
