The curious tale of domain links
After tinkering with my design (as you do), the new version showed just fine without www in the address, whereas the previous incarnation was showing with www. I noticed because my timeline was showing links to my custom domain name below the post and leading to the previous design. Resolved by putting the www back into the Domain name mapping box (I’d temporarily taken it out) and lo-and-behold the timeline domain links have gone.
Also, nice to so my photos are back ;)
