When you see a website page, your browser keeps a version of that page and it is stored locally in your computer in the so called “Cache Memory”.
Then when you connection is slow or the Internet is busy and you request that page again, if it takes a long time to download, the browser takes the previous version stored in the “Cache Memory”.
To load the new real live version, you have to reload/refresh the page in the browser (or press F5 key) and alternatively clear the cache memory.
Each browser clears the Cache Memory differently.
To clear the Google Chrome cache memory:
From the Menu Button button in the upper-right corner of the Chrome window, choose “More Tools” > “Clear browsing data…“
Then reload again the page you want to visit in your browser.
