I updated WordPress to 3.4.2 on 9/20/12 and since discovered that the rss feed broke and none of the links to individual posts are working, neither the links on the front page of the blog nor from the feed. My blog is at http://blogs.soartists.com/ArtMatters/. Google Analytics shows a pittance of visitors (0-3/day) since the 20th, when I usually get dozens of visits each day (30-100). Syndication to Facebook via Networked Blogs is no longer working. Error Message: "Error accessing this link! Please verify that it's valid, and that your site is up. Websites that are too slow might also be inaccessible, in which case you might want to check with your hosting company." The site is up, and I was using this feed url: http://blogs.soartists.com/ArtMatters/?feed=rss2
Using http://blogs.soartists.com/ArtMatters/feed does not work, NWB says it cannot read the feed.
Using my Feedburner feed url http://feeds.feedburner.com/soartists/LiVL, the feed is detectable, but there's an error saying the posts are not legible, so it also does not work and Networked Blogs cannot syndicate it. In addition, the post title links on my Feedburner feed return 404 NOT FOUND error pages and do not send people to the blog at all. If you go to the blog and compare the entries to the Feedburner list of posts, you can also see that entries posted after 9/20 are missing.
Just reinstalled 3.4.2 and ran the rss-feed-fix plugin, but still no feed and all links to individual posts are still returning 404 not found errors.
I need help with this one! Thank you for your attention and assistance.
