/blog redirection

What redirect did you create, and what URL is it affecting that it shouldnt?

At first thank you very much for such a prompt response.

Coming back to query.

My domain name is https://www.broadplace.com

While setup by mistake all blogs went on non /blog urls for example

https://www.broadplace.com/postname

Now I want to redirect all the blog urls to https://www.broadplace.com/blog/postname.

As per the regex method you mentioned in the link, I did it, but

while redirecting blog urls, it is also redirecting page urls

for example
their is a page https://www.broadplace.com/contact-us

After enabling the redirect even this page redirects to https://www.broadplace.com/blog/contact-us which is incorrect.

I just want my blog posts to be redirected to /blog and not the pages.

I hope it is clear now.

There is no way to distinguish a blog post from a page using the URL so you will need to create a redirect for each post. The link you referenced does not provide an example for this situation.
