WordPress releases an update an average of every 2 months. Upgrades are typically to fix bugs and security issues. Upgrades also improve the performance and features for pages, posts, audio, video and other system upgrades. The two main components that need to be upgraded are WordPress core, plugins and themes so that everything continues to run smoothly.
Plugins are independent pieces of software developed by various developers outside of WordPress. As WordPress is updated, it’s the developer’s responsibility to keep their plugins up-to-date. This is why before even choosing to install a plugin, it’s important to research the plugin, read reviews and check the last updated performed. Once installed, it’s important to continue updating the plugin as developer’s make upgrades for compatibility with WordPress.
Another reason why it’s important to have a professional perform consistent WordPress maintenance is to prevent possible security breaches. When updates are installed, there are changes to your files making your site vulnerable to hacker attacks. Part of the maintenance process Impress with WordPress performs is consistent backups of your site. Backups are also performed before updates are made. As of September, 2013 more than 70% of WordPress installations were vulnerable to hacker attacks. Keeping your WordPress website core, plugins and themes up-to-date will prevent your website from being vulnerable to hacker attacks.
