If you have uploaded a new version of a file to your website but are still seeing the old version, this is likely due to caching. Caching is a process in which a copy of a file is stored on the user's computer or the server in order to reduce the amount of time it takes to load a webpage.
To resolve this issue, you can try clearing your browser's cache and cookies. If you're using a Content Delivery Network (CDN), you may also need to clear its cache.
If you're still seeing the old version of the file after clearing your browser's cache and cookies and your CDN's cache, it's possible that your web server is also caching the file. You can try restarting the web server to clear its cache.
If you're using a Content Management System (CMS) like WordPress or Joomla, you may also need to clear the cache within the CMS itself. In WordPress, for example, you can clear the cache by installing a caching plugin or by accessing the "Performance" section of the dashboard and clicking the "Empty all caches" button.
