We are having an issue with all of our basic forms on the our site. They do not appear to be posting correctly - They appear to be posting to the homepage of the site with a querystring parameter '?sf_cntrl_id=xxxxxxxxxxxxxxxxxxxxxx'.
(An example of the form markup can be seen in the attached image snippet)
The only reference to this when trying to research the problem was found at this link:
Can anyone suggest why this may be happening?
We are using Sitefinity 8.2
