Shamim's Plugins

Please see forwarder settings for email piping, there is a location field, you have to update that.

Cannot you send attachment? or you can send attachment but not show with message?

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

add_action( 'fep_directory_table_column_content_name', function( $user ){
	$shop_name = get_user_meta( $user->ID, 'pv_shop_name', true );
	if( $shop_name )
	echo $shop_name;
	else
	echo $user->display_name;
});

Currently there is no feature like that in this plugin. You may do it by custom code, but that will be complicated.

Are they receiving announcement emails?
Was it working before? From when it is not working?
Please give me screenshot of Front End PM PRO > Settings > Emails page.

You can use like

<a href="http://example.com/message/?fepaction=newmessage&fep_mr_to=1,2,5">Send Message</a>

Change example.com/message/ with your message page url

Please go to Dashboard > Front End PM PRO > Settings > General and set “Time delay” as 0

Then add following code in your theme’s (child theme’s if any) functions.php

add_action( 'fep_action_validate_form', 'fep_cus_diff_time_delay_for_roles', 10, 2);

function fep_cus_diff_time_delay_for_roles( $where, $errors ) {

    if( 'newmessage' != $where )
        return;
        
    $args = array(
        'post_type' => 'fep_message',
        'post_status' => array( 'pending', 'publish' ),
        'posts_per_page' => 2,
        'author'	   => get_current_user_id(),
        'date_query' => array(
            'after' => '-1 week'
            ) 
        );
    if( 'threaded' == fep_get_message_view() )
        $args['post_parent'] = 0;
    
    $posts = get_posts( $args );
    
    if( ! $posts )
    return;
    
    $roles = wp_get_current_user()->roles;
    
    if( array_intersect( array( 's2member_level1', 's2member_level2'), $roles ) ) {
        $errors->add('time_delay', __( 'You can send maximum 1 message a week.', 'front-end-pm' ) );
    } elseif( count( $posts ) >= 2 && array_intersect( array( 's2member_level3', 's2member_level4'), $roles ) ){
        $errors->add('time_delay', __( 'You can send maximum 2 messages a week.', 'front-end-pm' ) );
    }
}
