I have just recently upgraded to 5.6.0.1 and my clients website has a problem when you submit the form block. No response Happens. And you get redirected to another page. I tried manually redirecting the form to another page to see if I can get a response that way. But when i went into edit mode and to change the redirect page, the sitemap pulls up with no pages inside to pick. Has anyone else had this problem or know how to fix this? this website is urgent for me so any help will be much appreciated.
