Old Browser Cache
Sometimes, browsers will display a cached version of your website instead of the latest one. Generally, when you visit a webpage for the first time, your browser takes a while to load the content. But next time, the content is showed up at once. This is because the browser stores the information that doesn’t change, on your computer. This is called browser cache that speeds up the page loading.
However, the problem arises when you make a change on your website. Most of the browsers do not update the cached data, so it reloads the old content. It seems that the website is not updating – time to clear the cached page or pages.

Press CTRL + F5 or Cmd+R in Mac for Google Chrome. You can also empty the cache by moving to the settings. Settings → History → Empty the Cache. It will reload the page and show you the newly updated pages. 

Firefox – Click CTRL+SHIFT+R or navigate to Options → Privacy & security → Cached Web Content — Clear now

Internet Explorer – Hold the SHIFT button and click the REFRESH button. You can also do it from Gear wheel. Safety →Delete browsing History → Temporary Internet files and Website files. Then, click Delete.

Safari – Go to the browser menu, and click Safari → Reset → Empty Cache or click CTRL+ALT+E.

Opera – Go to Settings → Preferences → Advanced → History. Select the Disk Cache section and empty the cache by clicking Empty Now. You can also use CTRL+SHIFT+DELETE to open this menu and delete private data.
