Problem with creating and changing Chronoform

I want to make some changes to my existing form and it won't allow me to change. Even if I tried to create a new for, it refuses to create one for me. It kicked me out to the control panel. Any idea what happen?

I'm using the latest Chronoform on Joomla 1.7.

Hi jackptoke,

This seems to happen sometimes with server security settings that don't allow larger forms to be submitted. If you have suhosin installed please see this post
