Visual Composer, dysfunctional after WP update

Hello! I just updated my WP to the latest version. This prompted me to update my PHP. I did so. Now when editing my theme the visual composer isn’t working. I read through some older forums and found a resolution of installing “classic editor plugin”. I’ve loaded the classic editor plugin but it doesn’t seem to do the trick.

Any suggestions would be great.
