i installed 4720 and imported the backup of 4711. several times i couldnt get into webadmin, it came with username password incorrect. via the console i editted the conf file to reset te password. after this mod i had access to the webadmin.
under some circumstances it is possible that a backup from 4.711 breaks you 4.720 installation - we work on this. Please retry is with a vanilla 4.720 and a "hand-imported" configuration.
