This article desribes an issue some customers have when upgrading an Ektron site with Pagebuilder functionality.

For example:

On the template, there is an icon for printing the page. After the upgrade, the script behind the icon does not trigger and therefore does not work anymore.

In the console, you can see this message that was not there before the upgrade.

JQMIGRATE: Migrate is installed with logging active, version 3.0.0

If this issue is happening it is because there are some legacy scripts on the template conflicting with the upgraded Pagebuilder.  To better troubleshoot this issue you will need to disable aggregation and minification.  For more information please see here.
