WordPress is no doubt the most powerful and popular CMS in the world. It powers more than 25% of the entire web.

The most important factor you should keep in your top priority is the security of your website. The advantage of WordPress being open source is everyone can view the source code, be it the learners or hackers. Besides hackers, there are also some good hackers who deal with the security vulnerabilities whenever they spot it and fix the issues or report it to the WordPress developer teams. As soon as the report is received by the developer team, they work on the vulnerabilities and release the new updates which fix the issue.

If you keep using the same old version with security vulnerabilities, you might be the victim of the hack. So, make sure to keep your WordPress site up-to-date.

To keep you at a safe place, keep regular WordPress backups, you never know when something goes wrong and you might need it.

As you are well aware of the reasons why you should keep your WordPress site updated, now, the question arises, how are you going to do that? Don’t worry; we are here to help you with this too. Before moving on to the ways to update WordPress, learn what should you really update?

What should you update?

Using the latest version of WordPress does not mean that you should only keep your WordPress core updated. Keeping the WordPress installation up-to-date includes updating following three aspects of WordPress:

  • WordPress core
  • Themes
  • Plugins

Whenever an update is available, you will see a message at the top left part of almost every page of your administration panel. To check the availability of plugins and themes, you can simply visit the “Updates” section of your WordPress dashboard.

How to update your WordPress site?

Updating WordPress core, plugins and themes are simpler than it looks. As WordPress comes with built-in update notification system, whenever an update is available, it highlights the available number of updates which you can see when you log into the WordPress dashboard. You can keep your WordPress updated through three simple ways mentioned below:

  • One Click Update
  • Automatic Update
  • Manual Update

One Click Update

It is the simplest and easiest way to update your WordPress site. WordPress release 2.7 brought this wonderful feature to let you update your WordPress site with a single click of a button. One click update can be done by clicking the link in the new version banner, but, if you fail to find the link then, you can go to the Dashboard > Updates Screen. And then, click the “Update Now” button to continue the process and that’s it. You need not have to do anything, once the process completes, you will be up-to-date. Isn’t it so easy? This update works on most of the server and if you face any problem during the update process then, you should check your file system.

The thing to note: If you are running older version WordPress which does not have this one-click update feature then, you have to do it manually.

Automatic Update

WordPress introduced this cool automatic update feature with the release of WordPress version 3.7. This feature has really made it easier for you as you need not have to look for minor releases again and again and perform the update. Whenever a new minor version of the update is available, this feature automatically downloads the version and installs it alone. You need not have to do anything, not even click. This is the case when minor version releases, but, if the release is of major version then; you will have to update yourself. For example, if your WordPress version is 4.0 and the available version is 4.0.1 then, WordPress will update it automatically by itself but, if the newly available version is 4.1 then, you have to do yourself.

Automatic updates are useful whenever minor version releases and you must be aware by now how important it is to perform a minor update to fix bugs. Automatic updates are enabled by default, but, if you want to disable it then you can do so by adding a new constant in your wp-config.php file. You can also enable and disable automatic update by using a filter if you don’t want to touch your wp-config.php file.

Manual Update

Automatic and one-click updates are with no doubt easiest and most used ways to update WordPress. But, if you don’t want to use this approach and want to update your WordPress site manually then, follow the following step by step instructions. Before proceeding for the task, make sure to back up your installation.

  • Download the latest version of WordPress zip file with a single click on Download WordPress button.
  • Unpack the downloaded zip file.
  • Deactivate all plugins that you are using so that it won’t cause any problem during the update. You can go to the plugins page and hit Deactivate button.
  • Delete the old wp-includes and wp-admin files so that you can replace it with new ones.
  • Now, upload the new wp-includes and wp-admin files using FTP or your shell access in the place of previously deleted old files.
  • Upload the content of the new wp-content folder to your existing one, overwriting your existing files. Except the files being overwritten, your other files or folders will remain same, unaffected. So, do not delete them. Delete only the files being overwritten.
  • Upload all new loose files of the new version from the root directory to your existing WordPress root directory.
  • Visit your administration panel to see whether your database too needs an update or not. In some case, the database also needs to be updated. If you see a message with a link in you administration panel then, click on it to update your database.
  • The update process is finished now. So, go to your plugin page and activate all your plugins.

With these three steps, you can easily update your WordPress site. You can update your plugins in a similar way.  You can find plugins like Updater and Automatic plugin updates, which gives you the option to select the plugins which you want automatically updates and which you don’t.

Updating Theme Without Losing Customisations

Now that we know the customisations that we can lose when we update the WordPress theme, it is time to see how to save these customisations.

You can try the following fixes to reduce the number of customisations lost during a theme update.

1. Add a Code Snippet Plugin

Many code snippet plugins create a copy of your code. This way you don’t lose the codes and scripts that you have added to your website for smooth flow.

Here is the code snippet plugin that you can use to easily create a website without breaking the code. With this code in place, you don’t have to add code to the functions.php file. Instead, you can just add it to the plugin and it will keep a record of it even when you update the theme file.

2. Create a Child Theme

You can also create a child theme to save any customisations that you have added to your WordPress theme file. A child theme saves the customisations made to the stylesheet. So, when you update the original theme, the child theme is not affected. This means that the data on the child theme will remain safe and you can easily update and enjoy the new features that the theme offers.

3. Add CSS Code to Theme Customizer

Another way to keep the customisations to your theme safe is by adding them to the theme customizer menu. By default, almost every theme offers a theme customizer menu with custom CSS. If you add your code to this custom CSS section, the data is not deleted from the server even when the theme is updated. So, it is also a good idea to make customisations to the theme through the theme customizer option.

4. Create Backup of Functions.php File

Last but not the least, you can create a backup of the Functions.php file if you are not using the code snippet plugin. The Functions.php file keeps a record of all the scripts that the website will run when it is operational. To ensure that all the scripts on your WordPress website remain intact, just create a copy of the functions.php file on the server and rename it as ‘copy-functions.php’ file. You can then restore this copy if any issue occurs to the WordPress theme files of the WordPress core.

5. Use CSS Customizer Plugins

You can use a plugin called CSS Hero to easily customize the theme of your WordPress website. The plugin lets you easily change the style of each block, font, or asset on your WordPress website without charging a lot of fees. You can simply create an account with CSS Hero and try the trial version. Once you have polished the design aspect using CSS Hero, you can create a live version for your website.

CSS Hero also keeps a copy of all the changes you have made to your website recorded within the plugin. You can even create a copy of this information on your local drive or save it on a third party cloud server just for easy access.

List of customisations Lost During WordPress Theme Update

Here is a list of customisations that are directly related to the WordPress theme that you have currently installed and activated on your WordPress website.

Code Added to Functions.php file

If you have made any changes to the WordPress functions.php file, you can lose all those customisations when you update the WordPress theme. The best option to keep these changes safe on your website is to create a backup of the functions that you have added. If you are not sure what functions to back up, you can simply copy the whole functions.php file.

Changes Made to CSS Stylesheet in WordPress

You will also lose any changes that were made to the CSS stylesheet of the theme file. When a theme file is updated, the updates also impact the CSS stylesheet file. To make sure that your CSS file remains secure, copy all the CSS scripts that you have added to the theme. The theme stylesheet will restore to the default stylesheet and you don’t want to lose all your hard-earned efforts.

How do Theme Updates work in WordPress?

Each theme developer offers a new update for his/her theme almost every year. Some developers even release new updates bi-annually. It is at your discretion to update or not to update your theme but if you do update, then you will get many new features that were not available previously.

To find out if your WordPress theme requires updates, simply visit your site dashboard and click on the ‘Updates’ page. You will see the number of updates you have to add to your website.

CMS Updates

Similarly, you can also see the WordPress theme updates on the theme page. Simply click on the WordPress dashboard, click on Appearance > Themes > and then select the theme whose updates you want to view.


Now, you can easily update the WordPress theme. The only problem with updating it is that you can lose most of your website customisations made to the WordPress theme.

Which Method is Best for Updating a WordPress Website?

If you want to keep your WordPress theme customisations safe, then the best way to do so is by using a child theme. A child theme enables you to easily replicate the whole parent theme on your website and make additional changes to it. As a result, your customisations and the parent theme, both remain unaltered.

Final Thought,

If you have chosen WordPress platform as your CMS then, keeping it up-to-date is the most important part of managing your WordPress website. Updating PHP, core WordPress and all of your plugins protects your website from malicious attacks, comes with added cool features making it more efficient and smoother for you to use. This is the reason, why WordPress community is always working diligently and releasing new improved versions.

These are all the ways to update your WordPress website without losing your site customisations. If you follow these ways properly, you will be able to easily customize your website theme, make changes to the layout, and create backups of all the data through the FTP server. It is always important to backup your WordPress files using plugins before you update PHP, theme, core files, or plugins. This will ensure that all your customisations remain safe.

Updating WordPress to the latest version can be challenging but, if you follow the above-mentioned process step by step then, you will easily be able to update it without any hassle.
