Maybe check the table definition, eg. if the field length is too small to hold the hash? Just a guess...
You are right! Thanks so much! The field password of the node is a varchar (64) while in the DB MASTER varchar (200).
Thanks Till, I appreciate! Error was in the length of field password, 64 instead of 200, in the node DB, the master is ok. Did the latest ispconfig update not correct it?
Password field length is fine here on my system, which has been updated as well. Maybe one of the incremental SQL updates was not applied on your server.
