Permalinks in WordPress not working

1. Go to admin
2. Click Settings
3. Click Permalinks
4. Select Post Name (for clean permalinks) or default
5. Finally Click Save

This rewrites .htaccess and wordpress permalinks may work in most cases

if .htaccess is not created, make .htaccess with following

# 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

can you also confirm mod_rewrite is enabled in your server?
