Hi everyone,
I’ve just encountered this and decided as a quick fix, I would add some CSS to wp-admin, to allow me to see the hidden field. You could amend the CSS rules within your browsers Inspect Element each time if you’d prefer. This is what I used in my functions.php. As always, take a backup of any files before you alter them!
add_action('admin_head', 'my_custom_fonts');
function my_custom_fonts() {
echo '<style>
.user-pass2-wrap {display:block!important;}
</style>';
}
