Hi !
On this page there is several forms in popup(maker).
The redirection at form submission doesn’t work.
Normaly the popup is closed and new page or popup opens.
But I doesn’t work. There’s only the thank message. I tried many things to repare it but no change.
Can you help me to resolve this issue ?

The page I need help with: [log in to see the link]
