If you are running ccomment Core & you now have purchased a PRO subscription you might be wondering how to upgrade. It's really easy. You don't need to uninstall the core version. Just go to the download section on this site (downloads -> ccomment -> select the latest release), then download the ccomment PRO package. Now go to your site's backend and install the PRO package that you've just downloaded. We will recognise that you have the Core version and we'll do everything necessary to upgrade it.
The PRO package is only visible to users with active subscription. If for some reason you don't see the PRO package in the download section -> log out from our site and then login again!
