This plugin is great! I'm trying to get it to work on my own website. I've added the hidden field on step 1 and step 2, but when I go to the second page, I only get the error "Please fill out the form on the previous page".
The form isn't displayed at all, neither the other information on the page.
I've added add_filter('cf7msm_force_session', '__return_true'); to my functions.php.
Do you have any idea what I'm doing wrong? Thank you in advance!
