In order to give your Joomla site a clean URL that makes it user friendly as well as Search Engine Optimized, you need to change the “htaccess.txt” file, and simply rename it to “.htaccess”.
What is the htaccess.txt file?
It is part of the Joomla core download. You can find it in the root folder of your Joomla site.
How to change the file:
1)Login to your Joomla site backend via FTP (File Transfer Protocol)
2)Locate the Joomla Site root folder ie(httpdocs)
3)Locate the “htaccess.txt” file
3)Rename the file to “.htaccess”
4)Login to Joomla backend, and click on “Site” from the menu and go to “Global Configuration”.
5)Under the “Site” tab in the “Global Configuration” change the “Use Apache mod_rewrite” to YES
6)Confirm both the “Search Engine Friendly URLs” & “Use Apache mod_rewrite” are set to yes and SAVE
Now your URL’s should read clean (http://www.yoursite.com/information.html) instead of the previous
