I'm using plugin called Display widgets that helps me select on which pages i want some other widget to be visible or hidden. It adds a check-box and list of pages on other widgets, thus expanding capabilities of other widgets. It works fine with other widgets but with Custom meta i can't see those options and can't select on which page i want Custom meta to be visible (on Blog page only). Do you know why is that? Can i add some lines of code to custom-meta.php to enable that?
