I have no explanation as to how my Main Menu has just dissapeared! It was there mid June because I too screenshots of part of it to illustrate someone's questions on this forum (See post here) but today when I went to the website - the Menu was gone! See photo attached. Any ideas other than just build it again?

Well, I went to Menu Management and saw 2 menus there. One I recognized for some future use but the second menu (and I didn't note its name) did not look familiar. I clicked to edit it and there opened the same menu less screen. Then I went back to Menu Management and that second menu was missing from the list.

I went to the home page and… there was the menu in place and complete. I don't know what I did… but it seems to be fixed!! (?)

Hi friendly,

That's really weird.
My best guess is something erased the menu items. Maybe something outside of Composr was messing with the contents of the cms_menu_items table.
Then you saw 'Default' on the list of menu choices in Menu Management, and it let you copy the autogenerated menu (the Default menu) back through to the main_menu.
