many errors when PHP 7.2 enabled

When I attempt to enable php 7.2 on this domain, I get a ton of errors on both front and back end of site. When I switch back to 7.1, they disappear. I have successfully enabled 7.2 on other domains but this one is giving me troubles. Any help would be appreciated. Here are the errors that appear:
