I use mailchimp to attract traffic to my landingpages where the visitors can fill in a gravity form. Once people fill in the form, i only receive a blank notification. This is caused by the mailchimp tracking parameters, see an example of the URL below.
There are no errors (and blank notifications) if i test the form by directly visiting http://www.mydomain.com/landingpage/ without the parameters.
What can i do to fix this?
