Hi @popephabulous,

This is most likely caused by an out of date W3 Total cache plugin or an old/unused Object Cache being installed on the site, That's mentioned in the 4.7 master list of issues on the forums.
You'll need to update any plugins to the latest version and ensure that any wp-content/object-cache.php files are either removed or updated to the latest version available

We've fixed this in the current 4.7 branch and will be included in the 4.7.1 release in January. See #39132 for where we've fixed this.
If you'd like to test out the upcoming 4.7.1 release on your site before the release, it includes a fix for this and bunch of other issues, see the directions available here for installing the beta testing plugin.
