WP 4.2.1 – Avia editor will not load

I updated to WP 4.2.1 recently, running 3.1.3 version of Enfold.

Previously editing pages with the Avia editor was working. Initially everything was working correctly although it was taking 20+ seconds for the Avia editor to load.

now all I get is the spinning waiting icon waiting for the editor to load. Error showing in the console

Uncaught TypeError: editor.getScrollInfo is not a function

Previously support told me to comment out line #289 (new avia_tinyMCE_button($tiny);) in the /config-templatebuilder/avia-template-builder/php/template-builder.class.php file to correct an previous issue. I tried both ways 1 being commented out and 2nd un-commented, but neither change the behavior when editing a page.

also was told to add this wp-config.php – add (define(‘CONCATENATE_SCRIPTS’, false );)

Please advise
