My form uses security image, and the "Please check the required fields" shows all the time. Why?
You create a form, download the myform.zip file, and upload all php files to your website, but "Please check the required fields" keeps showing up regardless you fill in all required fields. The reason is the PHP session. Your web server's php session config might have some problems.
I suggest you fix the php session problem, otherwise, even the form works, but you won't be able to view or download form data. Because of the php session has problem, it can not keep your login session, so you will be redirected to the login form again.
