WordPress Redirection not working after Moving to Subdirectory

Question

Today I moved my wordpress website from Root Directory to Subdirectory in same domain. I moved all files to new subdirectory. I have also setup 301 wildcard redirection from Hosting cpanel

301 Wildcard redirection Setting -

Old Address - https://www.example.com

New Address - https://www.example.com/blog/

When I am visiting any post directly like https://www.example.com/blog/this-is-a-post then it showing correct post without any error but the problem when I am opening the same post without "blog" word ie https://www.example.com/this-is-a-post then it also showing correct post instead of redirecting it to https://www.example.com/blog/this-is-a-post .

And when I visit through Google then it visiting the old address only ie without the word "blog".

One more thing is occuring is redirecting https://www.example.com to https://www.example.com/blog which is also what I don't want because I have different html index file for homepage

URL Settings in Wordpress Dashboard -

WordPress Address (URL) - https://www.example.com/blog

Site Address (URL) - https://www.example.com/blog

Contents of .htaccess file:

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /blog/
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /blog/index.php [L]
</IfModule>

# END WordPress

Answer 1

After removal of .htaccess and index.php file of wordpress from Root directory and removal of 301 redirect from cpanel.. The problem is fixed. Now I have different welcome page in roodex.com and have wordpress blog in roodex,com/blog But Now the problem is When visit through Google search result then Google showing old post url links and after visiting through that it is showing "Not Found" instead of redirecting to new url.

Assuming you are only serving static files from the root of your site (ie. you don't have virtual URLs and a front controller like WordPress) then the best you can do is redirect any request for the root directory (outside of /blog ) that does not map to a physical file, to your /blog subdirectory and hope for the best. If the URL doesn't exist within WordPress either then you'll just get WordPress's 404 page.

I assume you have a .htaccess file in the /blog subdirectory that handles the WordPress requests?

So, in the .htaccess file in the root of your site (which I believe is now empty), try the following:

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule !blog/ /blog%{REQUEST_URI} [R=302,L]

Change the 302 (temporary) redirect to a 301 (permanent) when you are sure this is working OK. 301s are cached hard by the browser so can making testing problematic.
