There's an odd thing happening. Sometimes, in our Admin area, we lose all style. When I look at the rendered source, the head tag is empty. If I refresh my browser cache, the content returns. There doesn't appear to be an impetus for this. We are running the "seven" theme in our Admin area.
As of right now, I've only seen it happen when I submit a new menu item or edit a menu item in our main menu and the site is returning to the menu list. Could it be that our menu is too big for some reason?
Any suggestions would be greatly appreciated.
