Comment (by laserjobs):

 I know you have probably heard this before but it is a live site I really
 can't test with. Is there another way to check without having to change
 themes out or disable plugins? Can I search files for "wp_trim_words()"
 because I found that the wp-content/themes/smart-mag/lib/posts.php file is
 common to all those warning and is the only reference I found to that
 function in themes and plugins?
