“These warnings usually indicate your site is using an old version of a third-party code snippet such as:http://gravitywiz.com/better-pre-submission-confirmation/
If you aren’t using that code snippet you’ll want to run through a theme/plugin conflict test:http://www.gravityhelp.com/documentation/gravity-forms/knowledge-base/troubleshooting/testing-for-a-themeplugin-conflict/”
