According to our Version Compatiblity page, the current WP Bakery Page Builder version we provide and support is 6.1. If you wish to install that version, make sure X and Cornerstone are up to date. Then, uninstall WP Bakery Page Builder and install it again via X > Validation.
I wonder what specifically are the issues though. If you’re experiencing layout issues and are using X Integrated elements, enable the Legacy X Integration in WPBakery Page Builder Settings > General. This was mentioned in our past release note
If you’ve edited the page without enabling the X Legacy Integration option and you see that the elements are combined in WPBakery’s text element, follow the solution shown in the video below.
