Hello,
I have looked through LF Answers and can't seem to find how to resolve the issue a customer is having with Public User accessing Forms through the Portal, who are hitting the below error, due to length of time, they have the form open:
Invalid form data was sent to the server. This can occur if the form is out of date. Please refresh this form and try again. [LFF2106-InvalidDataSent]
I see posts that talk about updating IIS or Web Config files, but these do not speak to the settings for publicly facing forms I believe, filled out by the Public.
Appreciate any feedback,
Jeff Curtis
