I noticed that some "Possibly related posts" on my blog link back to my own blog (which is fine), but add "www" in front of the URL (http://www.airodyssey.net instead of http://airodyssey.net). I know the URL is without the www (even if both work), and my main blog in my profile is without the www.
Also, the old URL still appears (back when I was testing WordPress.com to see if I'd move my existing website there). So some "Possibly related posts" still show up as http://airodyssey.wordpress.com
Go to the bottom of this post to see examples of both issues:
Are both of these known issues? Will it cause me any problems?
The blog I need help with is airodyssey.net.
