I converted a static site to wordpress. The naming structure changed (ie, no .html on the pages) so I did a 401 redirect. Everything disappeared from the SERPs. So I went back to the old .html naming structure. Now, when I google the actual URLs, Google will list them. But for any search..EVEN if I search the actual titel..the pages are GONE. Made a site map and submitted via google webmaster tools...twice. But my pages never appear in the serps???
