can you fix php notice and deprecated warning for future updates?

at buddypress-who-clicked-at-my-profile.php:

in function widget($args, $instance) {
add
$content = "";
for initialize the variable $content

fix
WP_Widget is deprecated from version 4.3.0! use
__construct() instead.

old method:

function BuddypressWCAMP_Widget_showMyVisitors() {
        $widget_ops = array('classname' => 'buddypresswcamp', 'description' => __('Show visitors of my buddypress profile page', 'buddypresswcamp'));
        $this->Widget('buddypresswcamp-widget-showMyVisitors', __('Show bp profile visitors', 'buddypresswcamp'), $widget_ops);
    }

new method

function __construct() {
        $widget_ops = array('classname' => 'buddypresswcamp', 'description' => __('Show visitors of my buddypress profile page', 'buddypresswcamp'));
        parent::__construct('buddypresswcamp-widget-showMyVisitors', __('Show bp profile visitors', 'buddypresswcamp'), $widget_ops);
    }

tnk y 🙂
