If you use the “view page source” function on your browser you will notice that by default Joomla 2.5 is namechecked under a generator tag. Anybody can use the “view page source” and therefore anybody can tell that your site is a Joomla one.

 

Adding the following code to the header section of your template's index.php file replaces the generator tag.


<?php $this->setGenerator('Place your replacement text here'); ?>
