If you want to know the version of WordPress used for any website without logging in, you can easily do so by viewing the source code of any page on the site. This method is ideal if you don't have access to the backend. When you log in to WordPress, you can find the version number in the bottom right corner of any page. If it's not there, try going to the panel's home page.
Another way to check which version of plugin you are using is to visit the plugins page in the WordPress administration area. There, you will be able to see the version of the plugin under its name for each plugin installed on your WordPress site. Finally, you can see your version of WordPress in About WordPress. Hover over the WordPress icon in the upper left corner and select About WordPress.
This page will provide details about your version of WordPress, including new features and contributor credits. The easiest way to find out which version of WordPress you are using is through the WordPress Dashboard. Log in to the dashboard area and go to the Updates section, which can be found in the left bar. You can also check your version of WordPress with WP-CLI.
Connect to your host via SSH (Secure Shell) protocol and type cd html to navigate to the correct directory. It's important to keep your website updated with the latest version of WordPress as it releases multiple updates every year. This will help keep your site secure and ensure that it runs smoothly. If you haven't checked it in a while, it's a good idea to do so as older versions are more susceptible to malicious attacks.
You can check your current version of WordPress from the Linux command line that you can access via SSH.
