How to Update a WordPress Theme<\/h2>

If you have a customized file or custom code inside your theme folders, you’ll want to skip ahead to the next section. Otherwise, you’ll lose any of the changes you made to the theme’s layout.<\/p>

However, if you’re like many WordPress users, you might have only made changes to the theme using its built-in settings – for example, via the WordPress Customizer or the Full Site Editor (FSE). If this is the case, you can follow the steps below to update your current theme.<\/p>

1. Create a Backup<\/h3>

Before commencing any major theme update, it’s important to create a fresh backup of your site.<\/p>

Even if you already do regular automatic backups, it’s a good idea to make sure you have an up-to-date version of your site on hand. That way, if anything goes wrong with the theme update, you can quickly restore your site to its original state.<\/p>

WordPress users can create a backup using a plugin or manually using FTP and phpMyAdmin. If you’re a Hostinger customer, it’s easiest to back up your WordPress site<\/a> from hPanel.<\/p>

Simply log in to your hosting account and access the hPanel dashboard. Then, find the Files <\/strong>tab in the sidebar and click on Backups<\/strong>:<\/p>

\"WordPress<\/a><\/figure><\/div>

Where it says File Backups<\/strong>, click on Select<\/strong>:<\/p>

\"Manage<\/a><\/figure><\/div>

Next, simply choose a date from the dropdown box and hit Next step.<\/strong> If you want to back up your entire site, select public_html<\/strong>. Alternatively, choose the specific files that you want to include in your backup:<\/p>

\"Download<\/a><\/figure><\/div>

Then, click on Download all files<\/strong>.<\/p>

\"\"<\/a><\/figure>

2. Create a Staging Site<\/h3>

Next, you’ll want to create a staging site. This is a copy of your live website that isn’t accessible to the public.<\/p>

A staging site is an ideal place for testing out new features or making changes to your website. It enables you to update your WordPress theme<\/a> in a secure environment without worrying about having to troubleshoot your site<\/a>.<\/p>

This way, you can make sure that the updated version is safe and doesn’t conflict with any other code on your site. Most quality web hosts provide staging tools with hosting solutions. At Hostinger, it’s included when you purchase a Business web hosting plan, which starts at RM12.99\/month<\/strong>.<\/p>

\"\"<\/a><\/figure>

As a Hostinger customer, you can access the staging tool from hPanel. Start by logging in to your hosting account, then follow these steps:<\/p>

    \n
  1. On the dashboard, go to WordPress → Staging<\/strong>:<\/li>\n<\/ol>
    \"Creating<\/a><\/figure><\/div>
      \n
    1. If the staging tool is included with your hosting plan, click on Create Staging<\/strong>.<\/li>\n\n\n\n
    2. Enter the subdomain that you want to use for your staging site and click on Create<\/strong>.<\/strong><\/li>\n\n\n\n
    3. Wait until your staging environment is ready. Note that this process can take up to 15 minutes to set up.<\/li>\n<\/ol>

      If your plan doesn’t include staging tools or you are with another provider, you can set up a staging environment in WordPress<\/a> manually or by contacting your web host. Another option is to use a staging plugin like WP Staging<\/a>.<\/p>

      3. Update the WordPress Theme on the Staging Site and Test<\/h3>

      Now, let’s cover how to update an existing theme. There are multiple options for this. First, you can update your theme from the WordPress admin panel. However, it’s also possible to update a WordPress theme manually using FTP or a File Manager.<\/p>

      How to Update a WordPress Theme from the Admin Panel<\/h4>

      The simplest way to update your installed theme is to do it from the admin panel or WordPress dashboard. To begin, log in to your website and head to Dashboard <\/strong>→ Updates<\/strong>. Then, scroll down until you reach the Themes<\/strong> section. You will see the list of whether there are any theme updates available. Simply check the box beside the active or inactive themes you want to update and click on Update Themes.<\/strong><\/p>

      \"WordPress<\/a><\/figure><\/div>

      Additionally, you can update your WordPress theme version by going to Appearance → Themes <\/strong>within your WordPress dashboard:<\/p>

      \"Update<\/a><\/figure><\/div>

      If updates are available, you’ll see a notification and a link on top of the theme that says Update now<\/strong>.<\/strong><\/p>

      How to Update a WordPress Theme Using FTP<\/h4>

      While the above method is certainly the simplest way to update your theme, you can also complete the task using a File Transfer Protocol (FTP). FTP enables you to connect to your website files remotely from a computer.<\/p>

      First, you’ll need to configure a secure FTP connection<\/a> using an FTP client<\/a> like FileZilla<\/strong>.<\/p>

      Once you’ve installed the program, open FileZilla and enter your FTP credentials<\/a> at the top of the screen. You can find the FTP login details within your hosting account.<\/p>

      After connecting to your website, locate the root folder of your WordPress site – this is usually public_html<\/strong>. Then, click on wp-content <\/strong>and open your themes <\/strong>folder:<\/p>

      \"Accessing<\/a><\/figure><\/div>

      Find your active theme within the folder. You’ll need to rename the file and add “_old” to the end of the file name.<\/p>

      Then, right-click on the file and select Download<\/strong>:<\/p>

      \"Download<\/a><\/figure><\/div>

      Now, you need to download the new version of the theme package to your computer. So, head to the theme’s landing page either within the WordPress themes directory or its official website. Download the theme’s ZIP<\/strong> file so that it’s ready to upload to WordPress.<\/p>

      Then, head back to FileZilla and return to the themes <\/strong>folder to upload your new file. At this point, the updated theme will be installed on your WordPress site, but you’ll still need to activate it.<\/p>

      On your WordPress dashboard, you’ll likely see two themes – one with the older version of the theme (that you added “_old” to) and one with the updated theme.<\/p>

      Click on Activate <\/strong>next to the new updated version of your theme:<\/p>

      \"Activate<\/a><\/figure><\/div>

      You may be prompted to overwrite the old theme files. In this case, proceed with the action. If you’re not asked to overwrite the theme, delete the old WordPress theme file<\/a> once you’ve successfully activated the new theme.<\/p>

      How to Update a WordPress Theme with File Manager<\/h4>

      If you don’t use FTP, you might be wondering how to update a theme with a File Manager. The process is similar to using FTP – the only difference is that you’ll be updating the theme directly through your hosting account.<\/p>

      As a Hostinger customer, it’s easy to update a theme through hPanel. Once you’re logged in to your account, access the website’s hPanel and click on WordPress <\/strong>in the sidebar.<\/p>

      Then, select Security<\/strong> and scroll down to the Installed themes <\/strong>section:<\/p>

      \"Installed<\/a><\/figure><\/div>

      Here, you can view all the themes installed on your website. The Recommendation <\/strong>column will notify when a theme update is available.<\/p>

      To update a theme, click on the three dots to the right of it and select Update<\/strong>:<\/p>

      \"Update<\/a><\/figure><\/div>

      There will be a message warning you that the update might affect your website. To continue, click on Update. <\/strong>The process will begin instantly.<\/p>

      No matter which method you choose, it’s always a good idea to test the new theme by previewing your site on the front-end once the update is complete.<\/p>

      4. Publish the Update<\/h3>

      After checking that the theme functions properly, you’re ready to publish the update from the staging site to the live site. To do this, go to WordPress → Staging<\/strong> on hPanel.<\/strong><\/p>

      You should find your staging site listed here. Next to the Manage staging <\/strong>button, there are three vertical dots.<\/p>

      Click on the dots and select Publish<\/strong>. Then, hit the Publish <\/strong>button on the pop-up window to proceed. Keep in mind that it can take up to 15 minutes for the changes to apply to your live site.<\/p>

      How to Update a Customized WordPress Theme<\/h2>

      Now you know how to update a standard theme using the most popular methods. However, if you’ve customized your WordPress theme<\/a>, you’ll need to use a different approach to avoid losing the changes you’ve made.<\/p>

      Perhaps you’ve added code to your theme’s functions file or added CSS to its stylesheet file. Or, maybe you made changes to the theme’s index.php <\/strong>or footer.php <\/strong>templates.<\/p>

      If you update your WordPress theme in the usual way, the theme files will be overwritten and you’ll end up losing customization. However, you can still update the theme while keeping its old customized version using the steps below.<\/p>

      1. Create a Backup and a Staging Site<\/h3>

      As we’ve discussed, it’s crucial to make a backup of your WordPress website in case anything goes wrong. However, it’s especially important when you’re updating a custom theme.<\/p>

      This is because you’ll need to use the backup theme files to apply the customizations to the new theme files or your child theme folder. To back up your WordPress site, you can utilize a backup plugin or hPanel. Visit step one of the previous section to find out how to do this.<\/p>

      Like updating a standard theme, it’s also a good idea to set up a staging site. This way, you can update your theme in a safe environment.<\/p>

      2. Create a Child Theme<\/h3>

      To update a WordPress theme that you’ve customized, you’ll need to create a child theme. This is the main difference between updating a standard vs customized theme. Child themes inherit the style, features, and functionality of the main or parent theme.<\/p>

      Once you set up a child theme, you can apply changes directly to it, and the parent theme will remain unaffected. Then, since the changes are stored in the child theme files, you can update the parent theme without losing the customizations.<\/p>

      To create a child theme<\/a>, you can use a plugin or build one manually using code.<\/p>

      It’s also a good idea to install WordPress locally<\/a> to develop a child theme. This way, you can make changes without affecting the live site.<\/p>

      3. Add the Customized Theme Files to the Child Theme<\/h3>

      Now, you might be wondering how to update your existing theme using a child theme. As we mentioned, you can create a child theme in various ways.<\/p>

      However, if you set up a child theme manually using a File Manager, you’ll need to add a stylesheet and functions file to your theme folder:<\/p>

      \"Adding<\/a><\/figure><\/div>

      This will enable the child theme’s files to inherit the styles and functions from the parent theme.<\/p>

      Then, you’ll need to identify any customizations that you made to the following parent theme’s files:<\/p>
