Hi Postgress,
I used to have a functioning PostgreSQL database, but upon reinstalling due to
computer issues, I am now getting this error after launching:
Traceback (most recent call last):
File "C:\Program Files\PostgreSQL\12\pgAdmin 4\web\pgAdmin4.py", line 98, in
<module>
app = create_app()
File "C:\Program Files\PostgreSQL\12\pgAdmin 4\web\pgadmin\__init__.py", line
347, in create_app
if not os.path.exists(SQLITE_PATH) or get_version() == -1:
File "C:\Program Files\PostgreSQL\12\pgAdmin
4\web\pgadmin\setup\db_version.py", line 19, in get_version
return version.value
AttributeError: 'NoneType' object has no attribute 'value'
I've tried everything from these stackoverflow forums
(https://stackoverflow.com/questions/43211296/pgadmin4-postgresql-application-server-could-not-be-contacted
and
https://stackoverflow.com/questions/67559636/pgadmin4-nonetype-object-has-no-attribute-value/67570989#67570989)
in order to fix it, however the error remains. I'm out of options, hopefully
you know the answer.
I tried it with both PostgreSQL 11, 12 and 13. I'm using a windows 64 bit with
PgAdmin 4.
Kind regards,
Derek

I have installed PostgreSQL 9.6.2 on my Windows 8.1. But the pgadmin4 is not
able to contact the local server. I have tried several solutions suggested here
in stackoverflow, tried to uninstall and reinstall PostgreSQL 9.6.2 , tried to
modify the config.py, config_distro.py, and delete the files in Roaming
folder,i tried standalone pgadmin4 installation, but no success.However, in my
