Error when creating new version of application
You might see errors or have problems when creating new versions of an app if the app has too many obsolete versions. Visual Builder limits the total number of versions of an app to 100, which includes development, staged and obsolete versions. You cannot create a new version if it will result in the limit being exceeded.
Each time you publish a new version of an app, the previous version becomes obsolete. On the Visual Builder Home page, you can see the total number of app versions in the Versions column, next to the number of the current version.
To remove obsolete app versions, you must first move them to the Trash, and then permanently delete them. For details, see Delete a Visual Application.
