Can't access General tab


I am running UrBackup 2.2.11 in a jail on FreeBSD 11.1 (actually FreeNAS 11.1-U5). I cannot get to the General tab in settings. I am logged in as an administrative user with rights All to domain All. I have tried urbackupsrv reset-admin-pw. Mail, LDAP/AD, and Users all work. I also cannot get to any of the client or group settings. I have tried Chrome, Firefox, Edge and IE. It does not work in any of them.
Any suggestions are greatly appreciated!
