If this issue “bugs” any other openfire admins out there (The issue w/ missing images on the Form UI setting)
I fixed this by simply copying the “images” folder from the plugins\fastpath\web to the plugins\fastpath\web\forms directory. You will need to create the forms directory since otherwise it did not exist.
Under …/plugins/fastpath/web make a directory called “forms” and created a symbolic link to the images called images under the new forms directory. Alternatively you can copy the images directory to a new forms/images directory. Hope this helps.
