pages doesnt update

Hi,

I changed under WIDGEDT, the widget photo and text, but it keeps after saving showing the old one. You might say…the browser shows the cache.. BUT, if so, why when I tell a friend in another country to visit the page for the first time he also sees the old stuff?

does the server has cache too and doesn’t update? if so, I have Cpanel, where do I clean there the cache?

Thanks !!
