Versions not working
The C5 cache is found at -
Dashboard>> Systems and Settings>> Optimization>> Clear Cache
or- Use the 'Intelligent Search' and search for 'Cache', 'Clear' or 'Clear Cache'.
They wouldn't be active because the page is already published and in use. You can't remove the latest page without first selecting an older page... so..
Select the older page (the one you want to use) and 'Approve' it; then select the newest page (the one you want to get rid of) and 'Remove' it.
If the page you want to use is a few versions behind then follow the same process but select all the newer pages and remove those.
Note: You can only delete the new version after you have approved an older version.
I hope that all makes sense. I'm really tired so excuse my gobbledigook.
Let me know how you get on. If you still can't do it, send me a PM with login details and I'll do it for you. :)
Go to the sitemap in the dashboard, click on the page name, click 'Versions' and select the version you want.
You may also want to check your permissions. I'm guessing you are logged in as admin (because you can see the previous versions) so it should work but check them anyway.
What browser are you using? It may be worth trying a different browser?
You're very welcome.
