Let’s me show in a video how it’s work.

This guide will show you the step by step process for first installation/configuring

Depending on the “Permalink Settings” it’s possible for some pages that the categories urls are not accessible.
To fix this problem you should go to update the .htaccess file which is existed under WordPress top directory.

Normally if you click on categories you will get something like this:
<yourDomain>/odlinks/?_action=main&id=2&parent=1

If instead of the “/odlinks/” something else is placed for example “/97-revision-v1/”
you can update your the .htaccess file as follows:

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ – [L]
RewriteRule ^97-revision-v1/?([^/]*)?/?(.*)$ /index.php?pagename=odlinks=$1=$2 [QSA,L,R,NS]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
