I recently completed upgrading our servers to PHP 7.2.20 and was informed this morning that we have the following error on our website: "Call to a member function get() on null"

After some testing I realized that this was only on the pages where we have ccomment showing up. And as soon as I disabled ccomment, the error went away. (We have CComment PRO 6.0.7)

You can see the error for yourself by going to https://www.project-management-podcast.com/ and then clicking on any of the "Continue Reading" links/buttons on the homepage.

Any suggestions what might be going on here?
