Answer 1

Is your form being placed on a page whose template is an ASP.NET Master Page? I blogged about this particular error before, and for me the cause has always been that the <form> tag in the master page has an id of something different from aspnetForm. If you have a master page whose <form> ID is something other than aspnetForm then Sitefinity's forms won't work. This is because Sitefinity's form-submission JavaScript is hardcoded to look for that particular form ID.
