I have two WP sites that have many pages and navigation is very dependent on my being able to have a menu with sub-menus. The drag and drop feature worked fine for four months, but suddenly it's gone wonkers. I can usually still drag and drop a page to under the heading it should be under, but the second I save the menu it moves back. Plus now sometimes when I move something, it changes hierarchy and nothing I do will put it back. (i.e., a top menu level page moves into a sub-menu position and no matter where I move it to or move it under it will only stay in second position. Or vice versa.
These sites were working for a few months until this happened out of the blue. My top navigation menu is a mess. It's three lines of random pages, most of which are supposed to be under one heading.
If it makes a difference, I'm working with pages, not posts.
The only similar problem post I've found is two years old and allegedly a browser problem, but I haven't changed browsers. Has anyone else run into this? Know a fix for it? Have a suggestion? Know a good plugin? I tried using menu plugins once, but my site stopped working and I was told to disable all plugins, and a menu plugin seemed to be a main culprit. I've been trying to use the minimum in plugins since then, since the entire purpose of my site can't operate without one certain plugin and I don't want any conflicts.
Any assistance would be greatly appreciated!
My site are:
(unfinished, but still there and workable)
FYI on the first of the pages listed, if you check under the menu item "Instruments" you'll see the drop down menu listing all the instrument pages as it is supposed to. But, I had to remove the Products heading and so you see three lines of product pages in haphazard order.
