Error: mysql_num_rows() expects parameter 1 to be resource, boolean

Located at: https://stockmench.com

I got the same error. I fix it temporarily by updating the sml.php file as below:

/*
$exists = mysql_query(“SELECT * FROM “.$wpdb->prefix.”sml where sml_email like ‘”.$wpdb->escape($email).”‘ limit 1″);
if (mysql_num_rows($exists)<1) {
$wpdb->query(“insert into “.$wpdb->prefix.”sml (sml_name, sml_email) values (‘”.$wpdb->escape($name).”‘, ‘”.$wpdb->escape($email).”‘)”);
}
*/
$exists = $wpdb->get_row(“SELECT * FROM “.$wpdb->prefix.”sml where sml_email like ‘”.$wpdb->escape($email).”‘ limit 1″);
if (!$exists) {
$wpdb->query(“insert into “.$wpdb->prefix.”sml (sml_name, sml_email) values (‘”.$wpdb->escape($name).”‘, ‘”.$wpdb->escape($email).”‘)”);
}

Hope this help. Thanks.

Go to sml.php and replace with this your current code.

This will work 100%
