change this line in your index.php
on root from
require('./wordpress/wp-blog-header.php');
to
require('./wdps/wp-blog-header.php');
then make an .htaccess
file on root like this:
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /wdps/
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /wdps/index.php [L]
</IfModule>
# END WordPress
