Think I stumbled across a bug today. You can't have pages that have just numbers as names.
I was setting up a page called newsletters. Made a sub page called 007, with the address reading newsletters/007/.
The page then only loaded the parent pages content, newsletters.
I got the page to work as expected by renaming it to issue-007, with an address of newsletters/issue-007/
Is this permalink limitation a feature for some reason, or I have just found a bug.
In anycase it would be useful to be able to use just numbers.
