Yesterday I posted an issue discovered when DEBUG mode:
( ! ) Strict standards: Declaration of ftRecentViewedPosts::widget() should be compatible with WP_Widget::widget($args, $instance) in C:\wamp\www\allnewish\wp-content\plugins\posts-viewed-recently\recent_viewed_posts.php on line 222

To solve it we replaced line 128 in recent_viewed_posts.php as per
function widget($args, $instance1){
Maybe it ll help you or sbd else…
