I've recently updated a site from Craft 2 to 3. I'm getting this error after login in to the admin regarding Sprout Forms which was installed in my Craft 2 install. What can I do to get the back-end functioning again? The front-end is fine apart from the pages which contained sprout forms, which I've removed.
