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 if 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.
Refresh a page to Clear the Cache Memory
To load the new real live version, you have to clear the Cache Memory by reloading/refreshing the page in the browser, you can do this by:
- On Windows with Chrome:
- Standard Refresh, press the key F5 or press the keys Ctrl + R
- Hard Refresh, press the keys Ctrl + F5 or press the keys Ctrl + Shift + R
- On MacOS with Safari:
- Standard Refresh, press the keys Apple + R or press the keys Command + R
- Hard Refresh, press: Shift + Command + R
If this does not work you have to clear the browser cache memory, each browser clears the cache memory differently.
