When fields are disabled, the value comes through as null so we need to specifically check for it

This is to avoid accidental misconfiguration while copy/pasting the
password value.

There is no point pre-compiling the theme SCSS if it is not stored somewhere that is available
to all webserving nodes. Localcache needs to be backed by the MUC cache.
