Shamim's Plugins

I think 2 are different places. one output for shortcode and another output for main message page. For shortcode it is already filled with page title but main message page that is not happening. You can only hide shortcode message title and not main page message title using following code instead of #message_title{display:none;}
.fep-form-shortcode-newmessage .fep-form-field-message_title{display:none;} (works in version 6.4 or later)

Are you asking about “From Email” and “Piping Email”?
You can use same or different email address.

Can you give me access to your website so that i can try?

What you want to achieve here? You want to send a message to post author when a new comment is posted in his post?

I tried in my test installation with shanghai timezone setup and it shows correctly.
Please again check your timezone setup, if require change to UTC and save, again shanghai and save.
Then send a message, and check front end as well as back-end to check time of that message.
Go to Dashboard > Front End PM PRO > All Messages to check that message time in back-end.
If both places show wrong time, Then deactivate all plugins and change theme to default theme and send message and check time.

Let me know.

As you want to send message to users when post is published, you can use following code

function fep_cus_user_post_send_messaage($post){

        $author = get_userdata($post->post_author);
        $author_id = $author->ID;
	$post_title = $post->post_title;
	$post_link = get_permalink($post);
	
	
        if ($post->post_type !== 'post')
                return;
        if ( ! function_exists( 'fep_send_message' ) )
                return;
        // Prepare message data
        $message = array(
             'message_title' => 'title', //change with message title
             'message_content' => 'xxx', //change with message content
             'message_to_id' => $author_id
        );
	
        $override = array(
             'post_author' => 1, //change with message sender id
        );

        // Send message
       fep_send_message( $message, $override );      
}
add_action( 'pending_to_publish', 'fep_cus_user_post_send_messaage', 10, 1 );

Thank you for contacting.
Sorry to say that, it is a limitation of WordPress core. WordPress uses separate table for each sub-site. Right now i do not see any way other than manually changing code to achieve this.
