It’s essential to keep your WordPress site secure. How do you check which version of WordPress you are using? There are a couple of methods.
1) WordPress Admin Dashboard
Log in to your WordPress admin area and go to the dashboard. You can find the WordPress version in the “At a glance” summary box.
2) Page source meta tag
Most WordPress websites contain a HTML meta tag, although some security plug-ins will disable this behaviour. Simply view the page source and search for “generator”.
You can remove the generator meta tag by added this to your functions.php file remove_action(‘wp_head’, ‘wp_generator’);
3) wp-includes version.php file
This is my preferred method. It’s easier to use grep from the command line to scan all sites on a server. You can find the file here /wp-includes/version.php .
Use this from the command line to quickly scan all sites find . -name ‘version.php’ -path ‘*wp-includes/*’ -print -exec grep ‘$wp_version =’ {} \; -exec echo ” \; . Run inside your /var/www folder or other location .
