I have a client with an IWP registration page.
For some people who access this page on their browser, they will see the last person's registration info.
But FM has been set to do an immediate new record and commit once someone hits the submit button, so previous data would not display.
And we have done a complete cache clear, history reset, turn off the browser and restart and the data will still appear.
I don't see it on my browser, but the client says he and a couple of others have seen previous registration data.
It almost seems like there is a cache on the hosting site which is restoring old data, because we have done everything we can do have both FM and the browser clear and refresh.
