Works with this fix

If you hover your mouse to the right of the + symbol it will work and duplicate… But since I was designing this website for a client I had to find a fix so they could click the actual + symbol.

I ended up fixing this issue by adding some CSS so now you can hover over the actual + symbol.

Here’s the fix.

add this to your functions.php. Minor CSS fixes it.

function custom_admin_css() {
   echo '<style type="text/css">
.widget-top a.widget-action, .widget-top a.widget-action:hover {
    padding: 1px;
    display: inline-block;
}         </style>';
}

add_action('admin_head', 'custom_admin_css');
