The blogger of
As the crow flies (this blog has good photos, go check it out) asked a question about why is one of her post gets no results. I have seen many blog posts seem to have same problem from server logs, but this is the first time I got asked. Probably a good time to address the issue for you.
Here is a short answer:
When BRPS inquires about
- same label posts, or
- specific post's labels
to Google Blogger, sometimes, Blogger replies with 404 NOT FOUND. Which might mean there is
- no posts under such label, or
- no such post,
but there is actually some posts are filed under such label or there indeed has that post. The cause is unknown to me, and I am not able to resolve this. When this happens, it may result “No related posts found.” to your blog posts.
Fortunately, the problem is not permanent. If BRPS inquires again later, it may get the correct result if Blogger no long respond 404. But, since BRPS has 24 hours cache time for each post's labels and same label posts list, the result will have to wait at least 24 hours (up to 48 hours) to get updated.
Please bear with this issue if this badly happens on your blogger.
