Hello Adwin,
Thanks for writing in!
“navigate to WPBakery Page Builder Settings > General Settings and make sure "Legacy X Integration" is enabled. A common request we get is to not overwrite parts of the WPBakery Page Builder. We are committed to keeping supporting sites from the early days of X where Visual Composer was our page builder but we’ve consolidated all that integration code under one setting. It used to be enabled by default, but you will now need to opt-in to use it.”
After doing the updates, always remember to clear all caches (if you are using WP Rocket, WP SuperCache or W3 Total Cache) when updating so that the code from the latest release is always in use. This will help you to avoid any potential errors.
Hope this helps. Please let us know how it goes.
