sometimes doesn't load -resolved

sometimes the main horizontal navigation menu doesn't load. It did load all the time before we added some optimization (jotcache and some things with jch optimize) We do not have the javascript and css combining and that has helped a little, but there is still an issue at times skagit.kidinsider.com/

Hi
I refreshed the page multiple times and I see the menu
you can try to disable the cachein the module options, else you must check with the optimization extensions that you are using
