Hi there,
Just found this thread and I’m having the same issue using the Salesforce-Web-to-Lead plugin for Gravity Forms. Where can I find the settings for the Salesforce Web-to-Lead add on that allows me to try out the option krista06886 suggested (to check the Enable AJAX and Disable script output)? I see the settings page but can’t find those options. I would try the Salesforce API plugin but a higher version of a Salesforce account is required (I work for a non-profit and we have a limited license.)
Thanks in advance for your help.
