redirect to “undefined” URL

in eoi-functions.php you missed an space before “data” in line 122.
this results in <form […]class='[…]‘data-fca_eoi_list_id[…]

the data attributes get lost and the redirect url after the ajax call for the registration is undefined.
happens if you resave forms with the newest version.

quick workaround, functions.php:

function fix_fca_eoi_alter_form($html) {
  return str_replace("'data", "' data", $html);
}
add_filter('fca_eoi_alter_form', 'fix_fca_eoi_alter_form');

resave all forms after adding this code.
