In order to enable Mod_Rewrite for your site you should create a text file called .htacccess in the directory where you wish the rewrite rules to apply.
The first line of this text file should be:
RewriteEngine On
After that you can place your rewrite rules. Here are some examples for Joomla's SEF option:
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} (/|.htm|.php|.html|/[^.]*)$ [NC]
RewriteRule ^(content/|component/) index.php
Many applications come with ready to use rewrite rules that can be found in a file called htaccess.txt.
If you have problems with mod_rewrite, you may ask your web host for assistance. You can always count on SiteGround's Support for such problems.
