A Problem With Edited Posts

Dear Blogpersons:
Recently, when I edit a post and republish it the new version does not appear on my blog. Also some of the new posts are not showing up on the blog even though the screen prompts say the new post published OK. Other people are having these problems, too. I mentioned this to the Blogger Help Group but so far there are no suggestions that work. Is anybody else having this problem? Got any fixes?
Yours truly,
A Sad Blogger
