Thanks – sorry I must be missing something really basic here.
All I have done is created a new category colours and moved the existing category red to be a separate subdirectory.
So an existing post “a” that did have a url
/red/a
is now reference url
/colours/red/a
As far as I can see /red/a no longer exists so how can I delete it. ?
Or have I missed the whole point and should be downloading a plugin which in essence says any reference to urls beginning /red sre really /colours/red.
I’m confused
