Chonoforms and Easy Profile

Hi,
before installing Easy Profile, to add a user on FrontEnd I used Chronoforms (demo-joomla-registration), but now I have this error: "Error: 403 Access Forbidden".
This seems webserver restriction!
Why?

Hi armandocurcio,

Not the slightest idea.
What is the URL you see with the error?
If you set Site Error Reporting to Maximum do you see anything more useful?
Does the form still work if you disable Easy Profile?
