Hello everyone. Here's the situation:
The customer requested me to duplicate his website onto a different domain with different branding, content, and so on. The website is built on WordPress. To achieve this, I used the Duplicator plugin to create a backup and then uploaded it to my hosting on the new "working" domain. After making all the necessary changes, everything seemed fine. However, when I made a backup of the modified site and attached its domain to my hosting, I encountered an issue - the logo did not carry over.

To troubleshoot, I investigated and discovered that the browser was still reading the "old" CSS. I checked the CSS through the WordPress admin panel and confirmed that the necessary code was indeed present and updated. I attempted to solve the problem by replacing the logo name and updating it in the CSS, but this did not resolve the issue. The browser continued to display the old CSS code.

I performed these tests on three different browsers and two additional devices.

Could you please help me understand what might be causing this issue?

Based on the information provided, it seems like the issue you're facing is related to caching. Caching is a process that stores copies of frequently accessed files, such as CSS, to improve website performance. Sometimes, when changes are made to a website, the browser may still fetch the old cached files instead of the updated ones.

To troubleshoot this issue, you can try the following solutions:

1. Clear the browser cache: Clearing the browser cache forces the browser to retrieve the latest version of the website's files. You can typically do this by pressing Ctrl + Shift + Delete (Windows) or Command + Shift + Delete (Mac) and selecting the options to clear cache and cookies.

2. Clear the WordPress cache: If you are using a caching plugin on your WordPress site, try clearing its cache to ensure the latest changes are reflected. This can usually be done through the plugin's settings or by deactivating and reactivating the caching plugin.

3. Server caching: Some hosting providers implement server-side caching. In this case, you may need to clear the server cache or contact your hosting provider for assistance.

4. Change the file names: If clearing the cache doesn't work, try renaming the logo file or modifying its URL in the CSS file. This can help force the browser to fetch the updated version of the file.

5. Use cache-busting techniques: Adding a cache-busting query string to the file URL can help ensure the browser retrieves the latest version. For example, change "logo.png" to "logo.png?v=1".

6. Try a different device or network: In some cases, the caching issue may be specific to a particular device or network. Try accessing the modified website on a different computer or network to see if the problem persists.

If the issue persists after trying the above steps, there are a few additional troubleshooting options you can explore:

1. Check for any caching plugins: If you have any caching plugins installed on your WordPress site, make sure they are properly configured. Some caching plugins have specific settings related to CSS caching that may need to be adjusted.

2. Review the theme's customization options: Some WordPress themes allow for logo customization through their own settings or a separate customization panel. Double-check if there are any specific theme options where you need to update the logo.

3. Inspect the HTML source code: Use the browser's developer tools to inspect the HTML source code of the website and check if the correct URL for the logo image is being rendered. Look for any references to the old domain or incorrect file path.

4. Verify file permissions: Ensure that the logo file has the correct file permissions and is accessible to the web server. Incorrect permissions could result in the logo not being displayed.

5. Check for any CDN caching: If you are using a Content Delivery Network (CDN) to serve your website, there might be caching involved at the CDN level. Check the CDN configuration and clear its cache if necessary.

6. Consult with your hosting provider: If you have tried all the above steps and the issue still persists, it might be worth reaching out to your hosting provider for assistance. They can investigate if there are any server-level caching mechanisms or configurations that are causing the problem.

By systematically going through these troubleshooting steps, you should be able to identify and resolve the issue causing the logo not to carry over properly to the new domain.

You can attempt to establish a connection to CSS by using this method:
<link rel="stylesheet" href="css/main.css?ver=1"/>
Alternatively, you can simply modify the names of the files. This adjustment should result in a successful outcome.

Please verify the path leading to the styles, as it is possible that you are referencing outdated styles. In the browser's inspector, locate the linked styles and navigate to their source, or download them for further examination to determine if they are indeed outdated. Additionally, consider checking the styles at the specified address in alternative browsers after clearing the cache.
