The first issue is almost certainly due to caching. Looks like you are seeing cached pages of your blog when not logged in. Please ensure to empty the caches created by plugins like WP Super Cache or W3 Total Cache from their admin pages. (The Delete Cache button on the floating admin toolbar may not work — it doesn’t, on my blog). Also, clear your browser caches as well. Or try from a different PC.
