PHP Warning FS_Plugin::__construct()

I’ve seen this warning come up for other plugins I own, and they were able to resolve it. So I figured I’d bring it up.

Every page load is bringing up 10+ of the following warning, which I believe may be the result of using an outdated freemius reference.

PHP Warning?FS_Plugin::__construct(): The script tried to access a property on an incomplete object. Please ensure that the class definition “FS_Plugin” of the object you are trying to operate on was loaded _before_ unserialize() gets called or provide an autoloader to load the class definition in /…/wp-content/plugins/glossary-by-codeat/vendor/freemius/wordpress-sdk/includes/entities/class-fs-plugin.php on line 126

Thanks!
