Array Error with 4.3 update

Hi All,

Please excuse me if I’m posting this in the wrong place– first time here. Anyone have any ideas?

Whenever I save or update any page, I get the following error:

Warning: in_array() expects parameter 2 to be array, string given in /home/namicphilly/public_html/wp-content/plugins/download-media-library/download-media-library-admin.php on line 74

[The above line gets repeated numerous times and then:]
