Often the reasons that changes are not immediately visible is because of the cache running on your local computer. The Cache on your computer allows your computer to process things faster. It accumulates pages and files that you have been to and stores them locally. But sometimes you make a change to you website and you don’t immediately see that change.
To fix this problem is fairly easy:
For Windows based computers: Shift + Ctrl + F5
For Mac OS – Cmd + R
For IOS devices (iPhone):
Go to Settings
Find Safari on the list
Tap on Clear Cache
Scroll Down for Privacy.
