I am trying to use the mega menu. I can add a row but it will not allow me to drag a module. When I try to save with the mega menu activated, the mega menu turns off and the row disappears. I tried the site on my local computer and it did the same thing. However I installed the themis quickstart and tried the same thing and it worked. Do you know of any plugins or whatever that would interfere with the mega menu?

I found out if I disabled the Helix and Helix 3 framework then it works OK. Make sure you dont have the helix framworks installed if you have Helix Ultimate
