Axel!
I have seen the DEMO database, it seems ok.But I my production database need to do anything with this error related Institution and Professional Models. The error say : You try to access record that does not exist (Document type: gnuhealth:institution) see screen shot.
Then I check Luis comments on health.py as follow, but I need steps to do this can you help please.
# Upgrade to GNU Health 2.6
# Insert to the gnuhealth.institution model the existing
# institutions in party
# Users need to specify the new type and plublic level attributes of
# the institution after the upgrade.
# The code will be executed if the gnuhealth.institution model is
# empty. Normally there are two conditions for this to happen:
# 1) Upgrade from versions < 2.6.0 (the model did not exist)
# 2) The party / company / institution was not created during the
# installation. Although users should always finnish the installation
# wizards, sometimes it just does not happens.
