Not working with 3,8,1

Not working with wp 3.8.1, get the following messages when I update the access token

oAuth Access Tokens: 	Not Present Deprecated: Function split() is deprecated in /volume1/web/wordpress/wp-content/plugins/tweet-blender/lib/twitteroauth/OAuth.php on line 717 Deprecated: Function split() is deprecated in /volume1/web/wordpress/wp-content/plugins/tweet-blender/lib/twitteroauth/OAuth.php on line 721 Deprecated: Function split() is deprecated in /volume1/web/wordpress/wp-content/plugins/tweet-blender/lib/twitteroauth/OAuth.php on line 721 Deprecated: Function split() is deprecated in /volume1/web/wordpress/wp-content/plugins/tweet-blender/lib/twitteroauth/OAuth.php on line 721 Use your Twitter account to login.

and the widget shows:

Notice: Undefined property: stdClass::$retweeted_status in /volume1/web/wordpress/wp-content/plugins/tweet-blender/lib/lib.php on line 581 Notice: Undefined index: widget_show_follow_link in /volume1/web/wordpress/wp-content/plugins/tweet-blender/lib/lib.php on line 724 Notice: Undefined index: widget_show_reply_link in /volume1/web/wordpress/wp-content/plugins/tweet-blender/lib/lib.php on line 724

It works fine on another wp installation wp 3.6.1
