Menu items displaying vertically

Hello,

A few days ago, our main menu started to display vertically and all the child items are expanded. I can't seem to figure out how to fix the issue. We're using Maximenu CK and Template Creator CK with the site and everything was working fine up until a few days ago. I'm not 100% sure if it's Maximenu or the Template Creator that is causing the problem, but since the menu is the only thing not displaying correctly, I figured I'd post it here first.

The site is www.cotullachamber.com for reference.

I've included a screenshot of what the menu should look like as well.




Thanks in advanced!

Hi
please check in the level 1 items of the menu, if you have set one of the item as "column", remove it. You must not create a column on a root (level1) item
