cd /kohadevbox/koha/Koha/Illbackends/FreeForm
git checkout b_36243
3) Restart plack:
koha-plack --restart kohadev
4) Create a new FreeForm request, visit:
<staff_url>/cgi-bin/koha/ill/ill-requests.pl?method=create&backend=FreeForm

6) Edit that request, click "manage request" or if #1 visit:
<staff_url>/cgi-bin/koha/ill/ill-requests.pl?op=illview&illrequest_id=1
7) Click "Edit request". Click "Submit". Notice it errors "No CSRF token passed for POST"
