In some servers, the caching system keeps the caches even if you change and replace the files using the general update process. To reflect the update, you must clear the cache. For example, if you have a caching system like Litespeed cache enabled, you may turn this off temporarily and refresh the page. If it does not solve the problem, manually delete the folder resources/views and reupload all fines using FTP. It might help to regenerate the cache in your server.
