#1 settings_fields() displays hidden form fields, so it must be inside the form tag: 

<form method="POST" action="options.php">
	<?php 
	// page slug on which the form is displayed, 
	// same as the group name ($option_group) in the options API
	settings_fields( 'my-page' );   

	// page slug on which the form is displayed
	do_settings_sections( 'my-page' );  
	submit_button();
	?>
</form>
