Since WordPress recently released new 5.0 version, we have tested our themes, and there shouldn’t be any compatibility issues with Wordpress 5.0.
Gutenberg became the official WordPress editor from WordPress version 5.0. In case you still want to use Classic Editor, you can add it manually, and your page backend will look the same as before. https://www.screencast.com/t/QoCo8YcS
Here you could find more about it https://wpklik.com/wordpress-tutorials/how-to-keep-wordpress-classic-editor/
So, until we release new theme update where WP Bakery 5.6 version is included, you could reach our support team here to update this for you, or you could install Classic Editor plugin to continue working on a way you used to.
