Shamim's Plugins

I can see its working fine. See attached screenshot.
Do you see any other page? Which user you are logged in?

Please add following code in your theme’s (child theme’s if you are using) functions.php

add_action( 'fep_form_field_output_date', function( $field, $errors ){
    printf( '<input type="%1$s" id="%2$s" class="%3$s" name="%4$s" placeholder="%5$s" value="%6$s" />',
	esc_attr( $field['type'] ),
	esc_attr( $field['id'] ),
	$field['class'],
	esc_attr( $field['name'] ),
	esc_attr( $field['placeholder'] ),
	esc_attr( $field['posted-value' ] )
    );
}, 10, 2);

It needs custom code. You can contact me using https://www.shamimsplugins.com/hire/ if you need code help.

Do you use any plugins to create tours? Or use any custom code?

Add following code in your theme’s (child theme’s if you are using) functions.php

add_action( 'fep_display_after_parent_message', function(){
	if ( get_current_user_id() != fep_get_message_field( 'mgs_author' ) ) {
		printf( '<div>Sender Email: %s</div>', fep_get_userdata( fep_get_message_field( 'mgs_author' ), 'user_email', 'id' ) );
	}
});

By default it does not support export announcements data, But you can access directly to database and export from there. It needs some DB knowledge.

Where you want to show sender’s email address?

You need to echo from there. Like following (change as you require)

add_action( 'fep_form_field_output_date', function( $field, $errors ){
    echo 'This is date field';
}, 10, 2);
