Menu Structure Not Showing in WordPress 4.0

I'm so glad you fixed it! :) Yes, it's quintessential to developing to look at multiple browsers since they all interpret the code a tad differently. I'm so happy for you and you just opened my eyes to take into account browser plugins, since I hardly every troubleshoot turning them off & on.

I learned from this discussion as well. :) Cheers!

I've been in this forum and in the wordpress support forums, my add_theme_support( 'menus' ); is in my functions.php file, I've tried everything I've found online, I've added define('CONCATENATE_SCRIPTS', false); to my wp-config.php file, i've tried creating an if statements to load my javascript and jquery conditionally because it's supposed to be a jquery problem when the menus don't show up, I've tried plugins that are supposed to work, I've even reinstalled wordpress, both from my dashboard and downloading a completely new copy. I have no idea why it isn't working, I'm about to give up on this and just install a regular theme.

I haven't tried removing the other code from my functions.php file, but I have tried switching themes and it doesn't work when I switch themes either. Even when I re install it with another theme active the menu would still have problems. I was going to try again when I got home from work but I haven't really found any solutions online that have worked, especially with the latest version of WordPress.

At that point the only thing I can think that would not allow you to use the WP drag and drop functionality would be that you have Javascript disabled or your operating in an old version of IE. Right Click the page and view page info, to see if you have Javascript disabled.
