WordPress 4.7 was just recently released, named “Vaughan” in honor of legendary jazz vocalist Sarah “Sassy” Vaughan. For many websites owners today, upgrading should happen automatically.
Most host providers now automatically update and upgrade WordPress websites hosted with them. For these owners, there’s no need to worry.
However, for those managing their own websites, upgrading is as easy as a single click. When WordPress is installed on a server with correct permissions for files and folder, usually the webserver has full access, upgrading WordPress should be easy.
Logon to the admin dashboard, select Updates on the left menu and upgrade using the Upgrade Now button.
This should upgrade WordPress easily. To configure WordPress to automatically update and upgrade itself so you don’t have to worry about manually upgrading, follow the post below.
Upgrading WordPress via SSH command line
In other cases, upgrading WordPress isn’t as simple as clicking the upgrade button from the administrator dashboard. Some WordPress installations are so restrictive, the only way to upgrade is via the commandline.
