Why am I receiving a warning message while using a webform?
If you are using Google Chrome and are accessing an HTTP webform,starting in October 2017, users accessing the webform will receive a warning message telling them that the page is not secure. Google said, "Beginning in October 2017, Chrome will show the ‘Not secure’ warning in two additional situations: when users enter data on an HTTP page, and on all HTTP pages visited in Incognito mode."
What Can I Do?
This issue will occur for the Legacy Webform plugin. The newer Webform plugin utilizes HTTPS (not HTTP) and is thus secure. You will need to migrate to the new Webform plugin. Contact Support if you have any questions.
