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
