Regular updates are released for WordPress plugins and for the CMS itself. It’s usually best to install the latest versions of all the components on your website to reduce the risk of complications and security issues. As we’ve seen above, you can find out what WordPress version a site is running even if you don’t have admin access. With plugins on the other hand, you’ll need to log in to the back end if you want to check what versions are installed. However, that’s generally not a problem, as you’re probably only interested in the plugins running on your own site.
To check this information, open the dashboard and launch the “Plugins” section from the left-hand pane. The page lists all the plugins that you’ve installed, including the version number. If a new version is available, there’ll also be a note with an update link.
