.htaccess and Apache VirtualDocumentRoot

If you using VirtualDocumentRoot in your Apache set you need to make a minor change to your .htaccess rewrites to make them work 
- just add a slash before the url and it'll work 

refer below

from: 
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^/?([a-zA-Z0-9_]+)-([a-zA-Z0-9_]+)$ index.php?module=$1&view=$2 [L]

to: 
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^/?([a-zA-Z0-9_]+)-([a-zA-Z0-9_]+)$ /index.php?module=$1&view=$2 [L]
