This can be caused by a variety of factors such as caching, incorrect coding or using the wrong file name.

The good news is, header modification issues can be solved with just a few coding solutions. In this article, we'll explore the most common issues and provide step-by-step solutions you can use to fix them. Whether you're a seasoned developer or just starting out, these tips can help ensure that your website's header displays correctly and in a timely manner. So, let's dive in and learn how to solve header modification issues on your website!

Common Reasons for Header Modification Issue

If you're wondering why your website's new look isn't showing up despite making modifications to the header, there are a few common reasons why this might be happening:

  1. Caching issues – If your changes aren't showing up, it could be because your browser or server is caching the old version of your website. Clear your cache or try accessing your site on a different device to see if the changes appear.

  2. Missing or incorrect code – When making modifications to the header, it's important to double-check your code to ensure everything is in order. Even one missing character or incorrect syntax can prevent your changes from showing up.

  3. Conflicting code – If you have multiple plugins or scripts running on your site that modify the header, they can sometimes conflict with each other and prevent changes from displaying as intended.

  4. Incorrect file permissions – In some cases, the issue may be related to file permissions. Make sure that the files you're trying to modify have the correct permissions set in order to allow for changes to be made.

By identifying and addressing these common issues, you can ensure that your website's header modifications appear as intended.

Solution 1: Clearing Your Browser’s Cache

If you've made changes to your website's header but they're not showing up, the first thing you should try is clearing your browser's cache. Your browser stores files, images, and other website content in a temporary storage area called a cache. When you visit a website, your browser checks the cache first to see if it already has the content it needs to display the page. If the content is already stored in the cache, your browser will use it instead of downloading it again.

Clearing the cache removes all the content stored by your browser, so the next time you visit the website, the latest version of the page will be downloaded. Here's how to clear your browser's cache:

Google Chrome

  1. Click the three dots in the top-right corner of your browser.
  2. Select "More Tools" and then "Clear browsing data."
  3. Choose "All time" as the time range and make sure "Cached images and files" is selected.
  4. Click "Clear data."

Mozilla Firefox

  1. Click the three lines in the top-right corner of your browser.
  2. Select "Options" and then "Privacy & Security."
  3. Scroll down to the "Cookies and Site Data" section and click "Clear Data."
  4. Choose "Everything" as the time range and make sure "Cached Web Content" is selected.
  5. Click "Clear."


  1. Click "Safari" in the top-left corner of your screen.
  2. Select "Preferences" and then "Privacy."
  3. Click "Manage Website Data" and then "Remove All."
  4. Click "Remove Now."

Microsoft Edge

  1. Click the three dots in the top-right corner of your browser.
  2. Select "Settings" and then "Privacy, search, and services."
  3. Under "Clear browsing data," select "Choose what to clear."
  4. Make sure "Cached images and files" is selected and choose "All time" as the time range.
  5. Click "Clear now."

Once you've cleared your cache, refresh your website and your header modifications should appear. If clearing your cache doesn't solve the issue, try one of the other solutions we'll cover in this article.

Solution 2: Checking for Errors in Header.php File

The header.php file is the main file that controls the structure and layout of your website's header. Any errors in this file can cause your website's new look to fail to show up. Follow these steps to check for errors in your header.php file:

  1. Open the header.php file in a code editor. If you don't know where to find this file, check the theme's directory in your WordPress installation.

  2. Look for any syntax errors in the code. Syntax errors occur when the code is written incorrectly or doesn't follow the proper structure of the programming language. These syntax errors can cause your website to not display properly. Common syntax errors include missing semicolons, brackets, or quotation marks.

  3. Ensure that all variables and functions are properly defined. When variables or functions are not defined correctly, it can cause your website to not display the header properly. If you are not familiar with PHP programming language, it's best to consult with an experienced developer.

  4. Check for typos in the code. Typos can be the source of many coding issues, and can be easily fixed once identified.

  5. Save the changes and refresh your website. If your website's new look is still not showing up, try clearing your browser cache and refreshing again.

By following the above steps, you can check for any errors in your website's header.php file that may be causing your website's new look to not show up.

Solution 3: Using FTP to Update Header File

FTP (File Transfer Protocol) is a method of transferring files to your web server through a client software like FileZilla or Cyberduck. If you've made changes to your header file and it's not showing up on your website, using FTP to update the file could help.

Here are the steps to follow:

  1. Connect to your website using an FTP client.
  2. Navigate to your theme folder, which is usually located in the wp-content/themes directory.
  3. Locate the header.php file and right-click on it.
  4. Select "View/Edit" or "Edit" depending on your FTP client.
  5. Make changes to the header file as needed.
  6. Save the changes and close the file.

Once you've updated the header file through FTP, clear your website's cache and refresh the page to see the changes.

Keep in mind that using FTP to modify header files requires some knowledge of coding and website management. If you're not familiar with how to use FTP, it's best to consult with a web developer or hire a professional to make the necessary changes to your website.

Solution 4: Disabling Caching Plugins

Caching plugins are great for improving website performance, but they can also cause problems when you're trying to modify your website's header. Here's how to disable caching plugins to solve header modification issues:

  1. Identify the caching plugin you're using. Some common ones are WP Super Cache, W3 Total Cache, and WP Rocket.
  2. Deactivate the caching plugin. This will temporarily disable caching and allow you to see any changes you make to your website's header.
  3. Clear your browser cache. This will ensure that you're not seeing cached versions of your website's pages.
  4. Modify your website's header as desired.
  5. Reactivate the caching plugin. Once you're done making changes, reactivate the caching plugin to improve your website's performance again.

It's important to note that disabling caching can slow down your website, so it's best to keep it disabled for as short a time as possible. Additionally, you may want to consider clearing your website's cache after making changes to ensure that users are seeing the most up-to-date version.

Solution 5: Checking for Conflicts with Other Plugins

One common reason why a new header modification may not appear on your website is due to conflicts with other plugins. Having multiple plugins installed on your website can sometimes cause conflicts with certain features, including header modifications.

To check for conflicts with other plugins, follow these steps:

  1. Deactivate other plugins on your website one by one.
  2. After deactivating each plugin, check if the header modification appears on your website.
  3. If the modification appears after deactivating a certain plugin, then that plugin is causing the conflict.

Once you identify the conflicting plugin, you have a few options:

  • Delete the conflicting plugin if it's not necessary for your website's functionality.
  • Disable the conflicting feature of the plugin if there is an option to do so.
  • Contact the plugin developer for assistance in resolving the issue.

Taking these steps can help ensure that your header modifications appear on your website without any conflicts from other plugins.
