I'm really needing some help here as I have tried everything I can think of but this problem is still occurring.
So I have gone to create a menu and have added a couple of pages to the custom menu... then I try to drag one above the other or pull the top one down, but all I see is a long section of empty panels dragging down the page.
I've uploaded a screenshot to show what I am being faced with by clicking the blue text below (link not displayed correctly?)
Does anyone know why this is happening and how I can resolve this issue please?
Any ideas, help or advice greatly appreciated.
