WordPress is the most widely used content management platform out there today. Because of it’s popularity, it is the most targeted by malicious hackers. WordPress developers are excellent with keeping up with potential vulnerabilities, and send out patches with security updates quite regularly. This is great, but it’s also important when this happens to test sites and make sure everything is still running properly. Sometimes an update can conflict with a 3rd party plugin and cause a feature to stop working. This is all fixable if caught, but it’s something that needs to be monitored and scanned regularly for vulnerabilities.
Keeping your site secure is one of the most important things you can do for your site, and your visitors. One of the ways to ensure a safe site, is to always keep any themes and all plugins updated to the latest version.
