Make sure that you’re keeping your WordPress sites up-to-date!!!
WordPress 4.2.2 Security and Maintenance Release has been released, and addresses a number of bug fixes as well as patches a number of security exploits.
It’s very easy to upgrade. There are all sorts of plugins out there which will help you backup your database — do this first. Then go to your Dashboard and choose Updates, and apply the Update.
This update is not optional. If you fail to upgrade WordPress to v4.2.2, you are leaving your site vulnerable to malware, defacement, or worse…
And don’t forget that it’s equally important to keep your WordPress plugins updated as well!
