No success message after submitting form

Hi there,

I’m using MC4WP on my WordPress installation over at https://movetoamsterdam.com. On my site, I have multiple areas where I use a signup form. I use the same form (same form ID) in multiple locations on my site.

For example, on blog pages there is a signup form in a widget in the sidebar. The form works fine in the sidebar.

But on one page (https://movetoamsterdam.com/find-rental-apartment-guide/) the form is embedded in the page content and does not work properly. A user can subscribe using the form, but the form does not display a success message after the user submits the form. The page does reload—there’s just no success message.

Why could this be the case?

On this page, there should be only one instance of the form. And visually, there is only one instance. But I noticed in the page source that this form has more complicated code than the form that appears in the sidebar widget. I’m not well enough versed in the code to figure out exactly what the difference is though, or whether this would cause the problem that a success message doesn’t appear.

Thank you,
Peter
