The "An error occured when list personal users for application applicationid: Personal Profile Management System will not be used because it could not be initialized. Probably xmldb location is not properly set. [Connection refused]" error is caused by a wrong port setting in MuseAdmin.xml file.
Please check the $MUSE_HOME/admin/MuseAdmin.xml file, locate the tag and check if the port is the same as the one Muse HTTP server/Apache Tomcat (depending on the Muse version) is running on.
