My client has a site that was built with Visual Composer before Cornerstone came out. I’ve updated to the latest theme version, but VC didn’t update. It’s 4.9.2
“There is a new version of WPBakery Visual Composer available. View version 4.12.1 details or update now.”
Thanks for writing in! You can simply delete your current version of your Visual Composer plugin. Then head over to X Addons section within your WordPress backend and install the latest version from there.
