Me too, or in my case by taxonomy. So I could have Taxonomy: Animals > Lions create dynamic galleries of both all animals and all lions.

@jezzdalgarno – thanks – your approach worked.

I established the menu-item-id that was being generated in the top level item of the broken menu and deleted the row of that ID in the wp_posts table. (It wasn’t a real post)

That then generated another item as the top level in the menu, and I deleted that too.

And so on, trying the menus section on the dashboard each time, until it miraculously reappeared.

Not sure what damage I’ve done, but at least it’s usable again.

Same here, on 3.04. Deleting a custom post type has given me exactly the same symptoms. I can’t access the Menu section on the dashboard, same HTML generated as jezzdalgarno except for a different menu item name.

Could someone clarify how to do what jezzdalgarno did?

Having gone through the DB and deleted every trace of the menu_item_id and post_id my admin menus page is now displaying correctly again.

Or indeed any other solution that could un-break my site?

@dcwtexas: Did you get a solution? I think I want the same thing – to allow users to create a maximum of one page. Yes?
