When I use “form builder” within an “Astroid Layout Module”, the error “Invalid Form ID” appears when I submit the form.
PLEASE NOTE - Until now, I have only experienced this on my local server, where I develop my websites. Furthermore, it seems that there are no problems if I use the “Form builder” widget directly in the template layout.

Steps to reproduce the behavior:

1. Create a new “Astroid Layout Module”;
2. Create a section;
3. Add a “Form builder” element, inserting one or more fields, and then save everything;
4. Configure the module to appear on one or more pages of the site and then save it.
5. Open the site and go to the page where the form appears;
6. Fill in the fields and submit the form;
7. The alert message “Invalid Form ID” will appear.

Best regards,
