Updated to latest version while running 3.4.2, each NGG page shows overview page

Hi,

I recently updated to the latest NGG version while still running 3.4.2. After update, I noticed that each of my NGG pages, options, manage gallery, etc, shows the overview page when clicked and I can’t access any of the other pages. Is anyone else getting this as well?

Thanks
