There are a few different ways to check the version of WordPress you have installed:
1. Go to Dashboard > Updates, which can be found at the top left of the admin area.
2. The current version will also be indicated in the bottom left corner of the page within the admin area.
3. If you don’t have access to WordPress admin, you can check the version in the public_html/wp-includes/version.php file, which can be accessed through an FTP program. The installed version number will be shown next to the following code: $wp_version
