1. Rename the file "htaccess.txt" in your Joomla!'s base folder to ".htaccess".
2. This step may not be necessary. Open .htaccess in a text editor. Uncomment RewriteBase / (remove the first character, #). If Joomla is installed in its own folder, the enter the Joomla folder name after the backslash. e.g. RewriteBase /yourjoomlafolder.
3. Log on to your Back-end and open the Global Configuration.
4. Enable the Search Engine Friendly URLs option and Save. This option converts the URLs from the native Joomla! format to the SEF format.
5. Enable the Use Apache mod_rewrite/URL rewriting option and Save. This option uses the Apache mod_rewrite function to eliminate the "index.php" portion of the URL.
