Mega Addons For WPBakery Page Builder

All my pages show like that and some say their is an error when i deactivate the mega add-ons they open though most of the pages i use the plugin so it looks faulty again. is it because the wp bakery and word press are up to date and the add-ons are not.

I keep getting messages from word press that the mega add-ons will create an error. all this started after word press updated
