Thanks for taking a look.
I understand it's a huge menu however we've had it larger without any loading issues so I don't understand why we are having difficulty now.
We originally had more menu items with icons and images and it wasn't rendering so slowly.
The only thing that has changed is that we transferred the site over to SiteGround as per the client's request, it was originally hosted on BlueHost.
I have read and installed the recommended plugins from the above articles without any boost in performance.
I've also tried creating another smaller menu (5 top level categories) and that is also loading slowly.
So is this an Ubermenu issue? Would another mega menu be able to handle this many items better?
If so what would you recommend?
