Sometimes, you can view one post in your blog, but when you click on the URL of that post, you get a 404 error. Whey this happens?
This sometimes happens when a blog owner publishes a post with the current date, but then edits the post and changes the date of the post.
Each post URL contains the date published, and the link in your “Latest Posts” list will be wrong because of this. Examine the blog in question and you’ll probably find the post. If not, the edited date is in the future so make sure you visit again to read that post!
