I've got a strange problem that has arisen after changing the name of a parent page which was the name of a previous page that was deleted and completely removed from wp trash.
This page is now resulting in a 404 (not found) error along with one other page. Strange ?
I've defaulted back to the standard wp theme and stripped out all plugins and it does not resolve.
If I switch to default permalinks, everything is fine and all pages serve correctly.
I'm running nginx as a proxy only, so apache / wp is responsible for generating the cached version of the page in the first place, however it seems to not exist or never get generated ?
Also stripped back my htaccess to WP core and modified nginx conf files to no avail.
I ran a couple of SQL queries to check page ID and permalinks were correct and they looked OK.
Can anybody suggest what might be causing this ?

Pages - "Promotional" and "Services" are the problem pages.
