If you are doing changes in your CSS, javascript file or in your images and uploading them on your server but you cannot see changes live when you refresh your page that is not a problem. Actually your browser save images, javascript files and style sheets in cache that’s why you see no change on your live site cause browser is getting images, javascript and styles from its cache not new files of images, js and CSS from server if you are using Windows easy solution Press Ctrl+F5 and you will see all changes cause this will get new files not from cache. So if you are updating your website and can’t see changes live try ctrl+f5 or remove cache of your browser.
