The Issue is not just on a single page but on the whole website ,
I’m Attaching the Screenshots for your better understanding and named the screenshots:- My PC and Another PC.

So the thing is that i’m working on this site and it appears totally different from the website I’m making in any other PC than mine.

For example:- I’ve attached the screenshot of the Home Page , so the screenshot named MY PC is the Page I’ve updated and also it is the page i want, whereas the Screenshot named Another PC is the old version of the page but idk how it is still appearing like this whereas in every PC it should appear like the page in MY PC!
