cipriano2u on "[Plugin: Visual Form Builder] After upgrading WordPress to 4.2.1, unable to edit/view existing forms"

I was able to resolve this downloading the latest version and replace the Visual Form Builder Pro folder in the Wordpress wp-content>plugins folder.

I learned this from opening a ticket in VBPro's Support site:
http://support.vfbpro.com/support/login

They provided the latest download.

My ticket is http://support.vfbpro.com/support/tickets/3637

Good Luck!
