You can clear your cache to help prevent users from seeing older versions of pages in two ways.

1. CLEAR ALL THE CACHE (Won't harm your site but not the ideal way)

This will remove ALL cached pages from your cache folder. The cached pages will then be rebuilt by WP Rocket which will take a little time if you have a big site. While this is not the ideal way to do things here is how to do it.

a) Log in to your WP admin area
b) Look at the black admin bar at the top of the page and mouse over the link called "WP Rocket"
c) From the drop-down select "Clear Cache"

That will delete ALL the cached pages on your site and start WP Rocket rebuilding the cache.

2. CLEAR CACHE FOR A SINGLE PAGE (A few extra clicks but RECOMMENDED)

Rather than clear out all your cache because you have edited a single page you can also just clear a single page. So, for example, you have only updated your "About us" you can just clear the stored version of that one page to make sure your visitors see the latest version.

Here is how to do that.

a) Make sure you are logged into the WP admin area.
b) Go to the public part of your website and navigate to the page you just edited.
c) In the black bar at the top mouse over WP Rocket
d) Select purge this URL

That will just clear that single page rather than your whole cache. Next, log out of admin and visit the page like a visitor would that will re-create a new cached version of the page.

Job done!

Please bear in mind some browsers and even Internet service providers can continue to show cached pages of your site even when you have updated them. You can not control the caching of the user or their ISP what you can do if they are having trouble seeing a new addition to your content is get them to try the following:

1. Tell them to press the F5 key on their keyboard four or five times in quick succession. This will force a hard refresh of the page.

2. Suggest that they clear their cookies.

Failing that it may just be a case of waiting for their ISP to update or flush their cache neither you nor 3001Web can control that.
