I am having great difficulties with my Navigation Bar. I started out using the Habadasher online store theme, which gave me a central site title and the nav bar underneath it. Somewhere during my first attempts at building, the nav bar has moved to a drop down menu at the top right. I have changed themes several times- all the ones so far that preview with a fixed nav bar also give me the drop menu- and when a theme offers a choice on nav bar settings (eg. Slick) changing those settings don't change anything on my site. I even deleted my account and started again- no change, and then bought a one month Pro upgrade to see if it would improve. So far, no. Any assistance would be much appreciated.
