If you want to activate SEF URLs on your joomla website, and don’t want to use any component for this, you can do it very easy.
- login to the administration panel
- go to the -> Global Configuration
- in the Site tab activate the Search Engine Friendly URLs, by clicking on the YES radio button and hitting apply
It’s easy, and don’t need to use any component or plugin for this. You can also rewrite joomla URLs, but this is an other tutorial.
