I had the integration successfully working just 30 mins. ago, then all of a sudden my form is no longer appearing on the page, or in the Gravity Forms form editor. I know I am using the proper login and password, as I am logged into SalesForce using that login. I tried deactivating the "Gravity Forms Salesforce API Add-On" plugin, and my form re-appeard. I reactivated the plugin, it stopped working.
This is the only error message I can find on the Forms > Salesforce settings:
1. Select the Object to create when a form is submitted.
Refresh objects & fields
Could not load Salesforce contact lists.
Please help, thank you!
