Hello,
As I see Visual Composer editor is shown:

Please clarify your issue.
Also you need update WordPress to the latest version as well as all required plugins which you can download from this link https://www.8theme.com/download-plugins/ .
Don’t forget to create back up of your files and database before starting update process!
Thank you.
Regards,
Eva Kemp.
