My redmine is in URI example https://my.domain.rm/redmine/.
Your plugin use non relative path to URI like:
#admin-menu a.vault { background-image: url("/images/locked.png"); }
and if I try save parameters in vault plugin server return 404 code because save action make:
https://my.domain.rm/vault_settings instead of corrected in my redmine instance https://my.domain.rm/redmine/vault_settings
