    Link Image URLs for image fields have defaulted to /undefined

    Please note: in order to present a functional form to our users, we cloned our form and replaced the linked images with linked text. The form at the URL on this thread is now the cloned, corrected form, which works.

    When I check the link in the form, the URL is:


    This is the case for any URL entered:

    I will forward this to our developers to have a look.  We will let you know as soon as it has been fixed.
