how create 123/why-do-birds-sing (requires htaccess file) url structure

Question

What to put in .htaccess to make URLs look like /123/why-do-birds

Answer 1

You just have to upload an empty  .htaccess  file to your server. 
Once uploaded, go back to Q2A Admin panel, change the URL structure for that option and save it.

The successful operation of  .htaccess  depends on the setup of your server and site. If you are being told that neat URLs are not available in the administration center, you should review the solutions in the link below.

Answer 2

This work for me:

# In order for the web server to process this file it must be renamed to ".htaccess"

Options -Indexes
DirectoryIndex index.php

<IfModule mod_rewrite.c>
    RewriteEngine On
    #RewriteBase /

    RewriteCond %{REQUEST_URI} ^(.*)//(.*)$
    RewriteRule . %1/%2 [R=301,L]

    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^.*$ index.php?qa-rewrite=$0&%{QUERY_STRING} [L]
</IfModule>
