I'm using SS 2.4.7 with the userforms module. When adding a field to the form, after I click the 'Add' button I get a whole screen of unrendered HTML i.e. I see the HTML displayed on screen - no controls, no links, only HTML code. The only thing I can do is press the Back button. The strange thing is, the HTML output looks perfectly ok, and when I examine it by looking at the 'view source' it looks exactly the same as what is displayed on screen. Perhaps there is an extraneous control character somewhere in there but I can't see it.

I thought it might be a browser issue but the same happens in IE, Firefox and Chrome.

My apologies if this has already been posted and answered. I did a good search of these forums but as you can imagine, searching for questions about unrendered HTML in a CMS forum throws up 80 bjillion results
