I run this on my site and after run it again show that this blog is not set to good what is that mean, and how can I check it works or not.

Did you click "Revert Blog View Property"?

yes I click on it

I am on 1.7.5

You only have a problem if you get text that says "The current blog view is set to " and then has something in red (like the last line in the screenshot).  If it says "Good!" in green at the end, then your blog view metadata is not set and everything is as it should be.

Like the last line shown in the screen shot, how many  records with red text do you have?

Ok thanks to clarify the things I have no line in red all are green , thanks again.
