Thanks. You have given me lots to think about!
The Permalinks this guy created are quite long, like http://GoldSmart.ca/knowledge/knowledge-base/%category%/%post%
I notice that the Permalinks offered by WordPress tend to be quite short. Do spiders have difficulty crawling long Permalinks like that?
Thanks for the insight. Yes, I did mean Settings>Permalinks. I understand, they LOOK like folders but it is just a route to the post.
My site is already clobbered because I allowed someone to design me a new template. When they did it they also changed the Permalinks setting, unbeknownst to me, resulting in broken incoming links all over.
I am now restoring the site with a new template. I am hoping that by reverting to the Permalinks convention in place before this all began, some of these old incoming links may work again.
