I checked out your site, and confirmed by checking the download contents this site had given you.
Apparently when downloading VaultWiki from this site, our site did not put the js/vw/vw/min folder in the ZIP. This means that when using your site with minified Javascripts turned on, none of the minified scripts from the last version were overwritten. So you are currently running VaultWiki 4.1.0 RC 3 with Javascript from 4.1.0 RC 2 (or lower, depending how long this problem has been there).
We have fixed the problem with our website that was not including the minified Javascript files. Please download another copy of the ZIP and reupload the /js folder to your site. You may need to clear your browser cache after doing so.
