I have read on a website that there’s an important security update for WordPress. My blog is bestlinen.wordpress.com. Do I need to upgrade it? If so, how do I go about it?
Looking at the name of your blog, I can tell that it’s hosted on the WordPress website, so you don’t need to worry about upgrades, they will take care of that for you. Nice Sferra linens by the way. Anyway, if you were hosting your own hosting service, then it would be advisable to upgrade the blog as soon as possible.
Instructions to upgrade can be found on the upgrade page on the WordPress website, however things are much easier since the more recent versions of WordPress, as you can now upgrade with a single click and let your blog do all the work. The one thing to remember is that you should always backup your site before kicking off an upgrade. Just in case, you can never be too sure; can you?
