    Why Keep WordPress Core, Theme, and Plugins Up to Date?

    Here are five key reasons why experts advise developers to keep their WordPress core, themes, and plugins updated:

    1. Fixes Bugs

    Be it themes and plugins or WordPress itself, all are a piece of software, and software often has bugs. Even the most polished software can be plagued with function-breaking bugs as more features are added over the course of development.

    A bug is nothing but an error in the code of the software. It often causes functions to break when a computer executes that particular part of the code. These bugs can either break a specific function or affect the entire website.

    Although developers have rigorous bug testing processes, some bugs get past the radar. They also rely on the public to report any bugs.

    Once they are aware of the bug, they begin working on the fix. And the only way to deploy the fix is through pushing an update.

    So, if your website and its plugins aren’t performing as expected, be on the lookout for any new updates that may fix the issues.

    2. Ensures Compatibility

    We often take the Internet for granted, ignoring that it is like machinery with many independent parts, like servers, CMS, plugins, hosts, browsers, etc. All these components must coordinate to display even a simple web page on your visitor’s device.

    Although rare, changes in one component of this big machinery often create incompatibility with the other components. For instance, WordPress core may get updated with a new structure incompatible with existing plugins and themes.

    Similarly, changes in browser and hosting service can also make WordPress incompatible with your website.

    Developers update WordPress and plugins when such issues arise, ironing out any newly introduced incompatibility. That’s why you must always update WordPress core, themes, and plugins to the latest version.

    3. Improves Speed and Performance

    The next reason why you must update your WordPress installation along with themes and plugins is to improve their speed and performance.

    We all want a snappy and fast website, for a slow website negatively impacts user experience, forcing people to bounce to competing sites.

    WordPress and third-party plugin developers are aware of this fact and regularly work on improving their respective products.

    Plugins and themes are notorious for slowing down websites. So, developers often implement new performance improvements, be it removing unnecessary features, optimizing the code, combining scripts, etc.

    New changes made to the code are then pushed to users via updates.

    4. Enhanced Security

    According to a report, over 800 million websites use WordPress, which is around 43% of all the websites on the Internet. The platform’s popularity makes it an attractive target for cybercriminals and hackers.

    Besides, WordPress is a free and open-source software. That means hackers can easily analyze its code and identify possible vulnerabilities, which they can easily exploit.

    To ensure that WordPress, themes, and plugins are protected against cyberattacks, developers regularly provide security updates based on the latest threat definitions.

    That makes updating WordPress core and plugins a must.

    5. New Features and Functionality

    The last reason why you should regularly update WordPress core, themes, and plugins is to get access to all the new features and functionalities.

    As mentioned earlier, WordPress is a popular platform, but by no means is it the only CMS available to users. There are many CMS platforms WordPress competes against.

    Developers regularly introduce new features to WordPress to keep the platform exciting and unique.

    Besides, the WordPress ecosystem in itself is quite competitive. Third-party themes and plugins compete against each other.

    Features and functionalities become the biggest point of differentiation between two plugins or themes.

    So, if you prefer to access new features at the earliest, you must update WordPress core and plugins without delay.

    How to Update Your WordPress to the Latest Version?

    Now that you know why updating WordPress to the latest version is essential, let’s look at two ways to update your WordPress setup.

    1. Automatic Updates

    Updating WordPress doesn’t have to be a complex process. Instead, you will receive updates automatically and can install them with a few mouse clicks.

    Just follow the steps:

    Step 1. Log in to WordPress and click Dashboard > Updates.

    Step 2. Whenever a new WordPress update is available, you’ll see the following message – An updated version of WordPress is available. 

    You will also see a button Update to Version ###. Click it.

    Step 3. Now, WordPress will fetch the latest files and install them.

    It is important to note that your website will go into maintenance mode.

    That means your website will be accessible for visitors, but you won’t be able to install any theme or plugin.

    Step 4. Once the update is installed, you’ll be redirected to the WordPress Dashboard.


    You should also see a Welcome to WordPress banner with a link to release notes. You can access the link to see what’s new in the latest update.

    2. Updating WordPress Manually

    Besides using the built-in automatic updater, you can manually update WordPress using an FTP client.

    Here’s how:

    Step 1. Head over to the WordPress website’s download page and click the Download WordPress ### button, and a zip file with the latest WordPress files will be downloaded to your device.

    Step 2. Once the latest WordPress version is downloaded, access the zip file and extract its content.

    Step 3. Now login to your website server via FTP client and look for the wp-content folder.


    Step 4. Next, we must temporarily disable plugins. To do that, right-click the plugins folder and rename it.

    Step 5. Delete folders named wp-includes and wp-admin.


    Step 6. Now, upload the latest wp-includes and wp-admin folders from the zip file you downloaded earlier.

    Step 7. Upload all files from the newly extracted wp-content folder to your existing wp-content folder, overwriting the existing files.


    Step 8. Next, upload files to the public_html folder.

    Step 9. Now, we can reactivate the plugins by renaming the edited folder back to plugins.

    Step 10. Visit your wp-admin page, and you’ll be asked to log in. Enter your credentials, log in, and your website will have been updated to the latest WordPress version.
