Redirect an archive page to its relevant URL-friendly filtered page

Question

Welcome aboard,

This should be made with the PHP rewrite rule in WordPress functions, but if you don’t want to use PHP, you can use the .htaccess redirection.

RewriteRule ^blog/category/(.*)$ /blog/?_tag_thoughts=$1 [R=301,NC,L]

Change WordPress .htaccess code with code below

# BEGIN WordPress

RewriteEngine On
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
RewriteRule ^blog/category/(.*)$ /blog/?_tag_thoughts=$1 [R=301,NC,L]
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]

# END WordPress
