Another question... I had created a page that I then deleted, but the custom URL/Permalink can't be re-used. So now, for example, it directs you to "www.domainname.com/portfolio-2" instead of just to "/portfolio" even though the original portfolio page has been deleted. Same thing happens with a post that was created, then deleted, and recreated from scratch not allowing the use of the previous name.
Any advice is appreciated!!
