Pages to Posts

Hi,

I wanted to change my page http://www.bestsmartphonesinfo.co.uk/htc-wildfire/ to post. I used pTypeConverter to do so. It converted it to a post.

I then wanted to change the URL of the post to the one the page version had previously used ie http://www.bestsmartphonesinfo.co.uk/htc-wildfire/ because the post had used http://www.bestsmartphonesinfo.co.uk/htc-wildfire-2/
but WordPress will not allow the change.

I note that the homepage http://www.bestsmartphonesinfo.co.uk/ still has the permalink http://www.bestsmartphonesinfo.co.uk/htc-wildfire/ in the article title at the top and that the page still exists.

The old page that I converted is not present in my list of pages inside Worpdress admin so I cannot delete it.

How do I finally make the change from a page to a post, keeping the old url http://www.bestsmartphonesinfo.co.uk/htc-wildfire/ for the post?

Kind regards,

John
