That was it! Thank you.
I’m running Suffusion too and had the same Do not link to this page in the navigation bars
option set on one of my main nav headings, and on checking noticed that the same page was missing from the sitemap.
Entering the ID of that page and regenerating the sitemap cleared the “#”.
Checking the problem page it’s noticeable that the permalink is set by Suffusion as “#” when the “Do not link to this page…” option is set. It’s all so very obvious now…
Now Google & Bing can finally index the site correctly ??
Thanks for your help.
