Not sending email to users

I had a similar issue.

In my case, I am running multisite, and one function was grabbing the wrong table name because of the way WordPress prefixes tables in a multisite environment. The fixed function code is below:

function em_get_data_post($id) {
	//select post proprety
	global $wpdb;
	$tp = $wpdb->prefix;
	$bp = $wpdb->base_prefix;
	$result = array();
	$result = $wpdb->get_row("
		SELECT post_status, post_title, user_login, user_nicename,
				display_name,post_author, user_email, post_name, post_author,post_status
		FROM {$tp}posts, {$bp}users
		WHERE {$tp}posts.post_author = {$bp}users.ID
		AND {$tp}posts.ID = '$id'
	");
	return $result;
}

Hi itsalljustaride
Thanks for your answer. Where exactly do I insert the code.

Thanks ??
