This is going to be a short one. So after the update of WordPress 4.5 a lot of people, including myself, started having issues with Visual Composer not working. The fix is very simple and can be found here in this great video.
Basically you need to deactivate, delete and reinstall the plugin. As always BACKUP whatever you’re doing before you delete anything!
