I just recently installed WP and cforms on a new domain, and created my first form which is rather basic: a name, email, drop down list, and captcha code. I've read the documentation here, as well as the support docs, but I can't seem to find a solution. You recommended in a separate post to install Firebug and I've tried that too, but I'm not sure what I'm looking for.
Problem:
I bring up the page, in a fresh browser, enter the fields, and press submit. The form sits there. The data stays in the fields, the captch code changes, but nothing else happens. No database updates. No emails are sent. It appears as if the captcha code was entered wrong, but it wasn't. It seems to be hanging at "http://www.domain.com/#usermessage" in Firebug.
You instructed us to submit the form and watch it in Firebug under Console – Post/Response. I'm not an expert programmer, but I understand some of this. If I can just be assisted in the right direction. Can you explain what I'm looking for? Can I give you more info to help me find a solution?

Thanks!
