Using latest versions of Gravity Forms (v18.104.22.168) and v2.2.2 of the Salesforce Add-on and suddenly I cannot edit any of my forms. All that is being displayed are the actual form fields and elements with their labels. The right hand side panels used to add additional elements is not appearing.
However, creating a new form seems to be working fine.
I'm running WP 3.5 and have tried and experienced the same issue in IE, Chrome and FF.
Disabled all plugins, problem solved.
Isolated the conflict to Gravity Forms Salesforce Web to Lead Add-On (Version 2.2.2) and specifically, it's the Salesforce API Add-On plugin that is causing this issue.
As soon as I deactivated this plugin, the issue was resolved. Once activated again, the issue came back.
Looking forward to a fix! Thanks :)
