My Subpages redirect to Home

Subpages or any post are redirecting to Home page.
I tried following options:
* Permalink settings
* deactivating plugins

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

# END WordPress
If i need to edit .htaccess then help me to edit

But problem still remains. So please help me how to get out of this problem.

The page I need help with: [log in to see the link]
