Intermittently, every few weeks, the menu appears empty of items. I have not determined a pattern or cause. The menu no longer appears on the website in this state.

This fix is for me to add an item and save menu. Then all the items reappear.

As an example, I add this “Policies” page and save:

Then the original menu appears again:

I then remove the page I added, save again and the original menu appears and everything works as before.

Has anyone experienced this before?
