Mega Menu not working after update – Cutt-off Columns

Hello I posted to your pre-sale questions form as I could not login, but I managed to finally get a working password-reset link so will post my issue in the forum:

We noticed on one of our client sites http://www.drchugay.com that the mega menu (procedures, before & after) is all messed up. It’s collapsing the menu into one column and is being cuttoff. This only happens on the homepage. I found this post from a few days ago: https://kriesi.at/support/topic/mega-menu-not-working-after-update-to-enfold-3-0-4/ and have tried everything suggested but nothing has worked.

– Disabled all plugins, did hard refresh and test, did not fix
– Removed iframe (3D Animation) from homepage
– Removed layer slider from homepage
– Completely removed and replaced the theme folder with the current download from Themeforrest (I have a child theme implemented so I was sure to to also replace the header.php file in that folder as well)
– We have a cache plugin installed, but we have disabled it during the troubleshooting process

I’m not sure where else to go from here, but this is a fairly important client and we need to resolve this as soon as possible. Please let me know if you require backend access or anything else to help solve this issue.

Thank you so much, I look forward to your reply.
