I checked alfresco BD and find that the table "act_id_user" is empty. Maybe because of that I have such mistake? (have no ideas what exactly to write to create new user) Anyway where I can find correct login and password?
Based on the alfresco.log, it looks like Alfresco webapp did not start properly due to failed workflow deployment at startup. Try check org/activiti/db/mapping/entity/Deployment.xml?
