As Joomla CMS by default has a meta generator tag which shows that the website is developed using Joomla platform. For security, the purpose is it important to hide the meta generator joomla tag from the source code and stop letting users/hackers to know which version of CMS you are using. You can do the following to remove Joomla generator tag.
You can very easily find the meta tag generator in the page source code inside Joomla head
<head></head> tag. To view the HTML source code :
<meta name="generator" content="Joomla! - Open Source Content Management" />
You can remove Joomla generator tag from the Joomla website by either adding a few lines of code to the index.php file of the active Joomla template or by simply using a third-party plugin which will need no modification to any of the files.
$document = JFactory::getDocument(); $document->setGenerator('');
After Joomla update/upgrade if template gets updated, you might lose the changes that have been done to the template core files. So it’s better to use a third-party plugin.
As you know that we can install third-party plugins into Joomla. The simplest way to remove the tag is to install one. Just download, install and activate the plugin does the work.
We have recently developed a free Joomla Plugin called Remove Tag Generator which can remove both generator meta tag as well as the Robots meta tag from the Joomla source code. The plugin isn’t available in Joomla Extensions Directory. So, you can also search for other similar plugins and install it into your Joomla website.
